+### LSP - Language Server Protocol
+
+> https://en.wikipedia.org/wiki/Language_Server_Protocol
+
+> https://langserver.org/
+
+The Language Server Protocol (LSP) is an open, JSON-RPC-based protocol for use between source code editors or integrated development environments (IDEs) and servers that provide programming language-specific features like:
+
+- motions such as go-to-definition, find-references, hover.
+- **code completion**
+- **marking of warnings and errors**
+- **refactoring routines**
+- syntax highlighting (use Tree-sitter instead)
+- code formatting (use a dedicated formatter instead)
+
+The goal of the protocol is to allow programming language support to be implemented and distributed independently of any given editor or IDE.
+
+LSP was originally developed for Microsoft Visual Studio Code and is now an open standard.
+In the early 2020s LSP quickly became a "norm" for language intelligence tools providers.
+
+### Tree-sitter
+
+> https://tree-sitter.github.io/tree-sitter/
+
+> https://www.reddit.com/r/neovim/comments/1109wgr/treesitter_vs_lsp_differences_ans_overlap/
+
+Tree-sitter is a parser generator tool and an **incremental parsing** library. It can build a concrete syntax tree for a source file and efficiently update the syntax tree as the source file is edited.
+
+It is used by many editors and IDEs to provide:
+
+- **syntax highlighting**
+- **indentation**
+- **creating foldable code regions**
+- **Incremental selection**
+- **simple refactoring in a single file**
+  - such as join/split lines, structural editing, cursor motion, etc.
+
+**Treesitter process each file independently**, and it is not aware of the semantics of your code.
+For example, it does not know does a function/variable really exist, or what is the type/return-type of a variable. This is where LSP comes in.
+
+The LSP server parses the code much more deeply and it **not only parses a single file but your whole project**.
+So, the LSP server will know whether a function/variable does exist with the same type/return-type. If it does not, it will mark it as an error.
+
+**LSP does understand the code semantically, while Treesitter only cares about correct syntax**.
+
+#### LSP vs Tree-sitter
+
+- Tree-sitter: lightweight, fast, but limited knowledge of your code. mainly used for **syntax highlighting, indentation, and folding/refactoring in a single file**.
+- LSP: heavy and slow on large projects, but it has a deep understanding of your code. mainly used for **code completion, refactoring in the projects, errors/warnings, and other semantic-aware features**.
+
+### Formatter vs Linter
+
+Linting is distinct from Formatting because:
+
+1. **formatting** only restructures how code appears.
+   1. `prettier` is a popular formatter.
+1. **linting** analyzes how the code runs and detects errors, it may also suggest improvements such as replace `var` with `let` or `const`.
+
+Formatters and Linters process each file independently, they do not need to know about other files in the project.

+# Editors
+
+My editors:
+
+1. Neovim
+2. Emacs
+3. Helix
+
+And `Zellij` for a smooth and stable terminal experience.
+
+## Tips
+
+1. Many useful keys are already provided by vim, check vim/neovim's docs before you install a new plugin / reinvent the wheel.
+1. After using Emacs/Neovim more skillfully, I strongly recommend that you read the official documentation of Neovim/vim:
+   1. <https://vimhelp.org/>: The official vim documentation.
+   1. <https://neovim.io/doc/user/>: Neovim's official user documentation.
+1. Use Zellij for terminal related operations, and use Neovim/Helix for editing.
+1. As for Emacs, Use its GUI version & terminal emulator `vterm` for terminal related operations.
+1. Two powerful file search & jump tools:
+1. Tree-view plugins are beginner-friendly and intuitive, but they're not very efficient.
+1. **Search by the file path**: Useful when you're familiar with the project structure, especially on a large project.
+1. **Search by the content**: Useful when you're familiar with the code.
+
+## Tutorial
+
+Type `:tutor`(`:Tutor` in Neovim) to learn the basics usage of vim/neovim.
+
+## VIM's Cheetsheet
+
+> Here only record my commonly used keys, to see **a more comprehensive cheetsheet**: <https://vimhelp.org/quickref.txt.html>
+
+Both Emacs-Evil & Neovim are compatible with vim, sothe key-bindings described here are common in both Emacs-Evil, Neovim & vim.
+
+### Terminal Related
+
+I mainly use Zellij for terminal related operations, here is its terminal shortcuts I use frequently now:
+
+| Action                    | Zellij's Shortcut |
+| ------------------------- | ----------------- |
+| Floating Terminal         | `Ctrl + p + w`    |
+| Horizontal Split Terminal | `Ctrl + p + d`    |
+| Vertical Split Terminal   | `Ctrl + p + n`    |
+| Execute a command         | `!xxx`            |
+
+### File Management

+| ----------------------------------- | ------------------------------------------------ |
+| Save selected text to a file        | `:w filename` (Will show `:'<,'>w filename`)     |
+| Save and close the current buffer   | `:wq`                                            |
+| Save all buffers                    | `:wa`                                            |
+| Save and close all buffers          | `:wqa`                                           |
+| Edit a file                         | `:e filename`(or `:e <TAB>` to show a file list) |
+| Browse the file list                | `:Ex` or `:e .`                                  |
+| Discard changes and reread the file | `:e!`                                            |

+| --------------------------------------------------- | -------------------------------------------------- |
+| Move to the start/end of the buffer                 | `gg`/`G`                                           |
+| Move the line number 5                              | `5gg` / `5G`                                       |
+| Move left/down/up/right                             | h/j/k/l or `5h`/`5j`/`5k`/`5l` or `Ctr-n`/`Ctrl-p` |
+| Move to the matchpairs, default to `()`, `{}`, `[]` | `%`                                                |
+| Move to the start/end of the line                   | `0` / `$`                                          |
+| Move a sentence forward/backward                    | `(` / `)`                                          |
+| Move a paragraph forward/backward                   | `{` / `}`                                          |
+| Move a section forward/backward                     | `[[` / `]]`                                        |
+| Jump to various positions                           | `'` + some other keys(neovim has prompt)           |
+
+Text Objects:
+
+- **sentence**: text ending at a '.', '!' or '?' followed by either the end of a line, or by a space or tab.
+- **paragraph**: text ending at a blank line.
+- **section**: text starting with a section header and ending at the start of the next section header (or at the end of the file). - The "`]]`" and "`[[`" commands stop at the '`{`' in the first column. This is
+  useful to find the start of a function in a C/Go/Java/... program.
+
+### Text Manipulation

+## Install or Update
+
+After deploying this nix flake, run the following command to install or update emacs:
+
+```bash
+doom sync
+```
+
+when in doubt, run `doom sync`!
+
+## Testing
+
+> via `Justfile` located at the root of this repo.
+
+```bash
+# testing
+just emacs-test
+jsut emacs-purge
+just emacs-reload
+
+# clear test data
+just emacs-clean
+```
+
+## Limits
+
+- It's too slow to start up and install(compile/build) packages.
+  - I have to use emacs in daemon/client mode to avoid this issue.
+- It's too large in size, not suitable for servers.
+  - So vim/neovim is still the best choice for servers.
+- Emacs's markdown-mode works not well with tables, see:
+  - https://github.com/jrblevin/markdown-mode/issues/380
+- I use git command frequently, but doomemacs only autoupdates status of git diff / treemacs when using magit.
+  - I have to learn magit to avoid this issue...
+- GitHub's orgmode support is not well, Markdown is better for GitHub.
+  - Use markdown for repo's README.md, and use orgmode for my personal notes and docs only.
+
+## Cheetsheet

+# Helix Editor
+
+Neovim is really powerful, and have a very active community. I use it as my main editor, and I'm very happy with it. I use it for everything, from writing code to writing this document.
+
+But its configuration is a bit complex, and finding the right plugins, writing configurations, and keeping everything up to date is not easy.
+
+That's why I'm interested in Helix, Helix is similar to Neovim, but it's more opinionated, and it's batteries included.
+Whether I'll switch my main editor to Helix or not, it gives me a lot of ideas on how to improve my Neovim workflow.
+
+## Tutorial
+
+Use `:tutor` in helix to start the tutorial.
+
+## Differences between Neovim and Helixer
+
+1. Selecting first, then action.
+    1. Helix: delete 2 word: `2w` then `x`. You can always see what you're selecting before you apply the action.
+    2. Neovim: delete 2 word: `d`. then `2w`. No visual feedback before you apply the action.
+1. Helix - Morden builtin features: LSP, tree-sitter, fuzzy finder, multi cursors, surround and more.
+    1. They're all available in Neovim too, but you need to find and use the right plugins manually, which takes time and effort.
+1. Helix is built in Rust from scratch. The result is a much smaller codebase and a modern set of defaults. No VimScript. No Lua.
+    1. Neovim contains a lot of VimScript, and lua is too dynamic, it's hard to debug.
+    1. Personally I'm glad to take a look at a Rust codebase, but not a VimScript/Lua codebase.
+1. Neovim have a very activate plugin ecosystem, and it's easy to find plugins for almost everything.
+    1. Helix is still new, and it even do have a stable plugin system yet. A PR to add a plugin system is still envolving: <https://github.com/helix-editor/helix/pull/8675>
+2. Neovim has intergrated terminal, and it's very powerful. It's quite similar to VSCode's intergrated terminal. I use it a lot.
+    1. Helix doesn't have a intergrated terminal yet, as it's complicated to implement. Users are recommended to use tmux/Zellij or Wezterm/Kitty to implement this feature instead.
+    1. <https://github.com/helix-editor/helix/issues/1976#issuecomment-1091074719>
+    1. <https://github.com/helix-editor/helix/pull/4649>
+    1. **My Neovim often gets stuck when I switch to [toggleterm.nvim](https://github.com/akinsho/toggleterm.nvim), this Helix issue made me consider to switch from this Neovim plugin to Zellij**.
+1. Helix do not have a tree-view panel, it's recommended to use Yazi/ranger/Broot instead, and open Helix in them.
+    1. a tree-view plugin may be added after the plugin system is stable, but no one knows when it will be.
+    2. and some Helix users stated that they don't need a tree-view plugin, Helix's file picker is useful and good enough.
+1. It seems Helix lacks a global substitution command, you should run it in another window(via wm or Zellij).
+    1. <https://github.com/helix-editor/helix/issues/196>
+    1. Neovim's substitution command allow you to preview the changes before you apply it, and it's very useful. if I switch to Helix, I'll need to find some other tools with similar feature(such as https://github.com/ms-jpq/sad).
+1. Complexity and Maintenance Costs vs Batteries Included: <https://github.com/helix-editor/helix/discussions/6356>
+
+
+I think Use Helix/Neovim within a terminal file manager(Yazi/ranger/Broot) and Zellij is a good idea. 
+It's quite different from the workflow I migrated from VSCode/JetBrains before, I'm very interested in it.
+
+In Neovim I can make the workflow similar to VSCode/JetBrains by using some plugins, but Helix forces me to get out of my comfort zone, and try something new.

+# Encryption
+
+We have GnuPG & password-store installed by default, mainly for password management, authentication & communication encryption.
+
+We also have LUKS2 for disk encryption on Linux, and [rclone](https://rclone.org/crypt/) for cross-platform data encryption & syncing.
+
+[age](https://github.com/FiloSottile/age) may be more general for file encryption.
+
+[Sops](https://github.com/getsops/sops/tree/main) can be used for file encryption too, if you prefer 
+using a Cloud provider for key management.
+
+
+## Asymmetric Encryption
+
+Both age, Sops & GnuPG provide asymmetric encryption, which is useful for encrypting files for a specific user.
+
+For morden use, age is recommended, as it use [AEAD encryption function - ChaCha20-Poly1305][age Format v1],
+If you do not want to manage the keys by yourself, Sops is recommended, as it use KMS for key management.
+
+## Symmetric Encryption
+
+Both age & GnuPG provide symmetric encryption, which is useful for encrypting files for a specific user.
+
+As described in [age Format v1][age Format v1], age use scrypt to encrypt and decrypt the file key with a provided passphrase,
+which is more secure than GnuPG's symmetric encryption.

+# GNU Privacy Guard(GnuPG)
+
+> Offical Website: https://www.gnupg.org/
+
+The GNU Privacy Guard is a complete and free implementation of the OpenPGP standard as defined by RFC4880 (also known as **PGP**). GnuPG allows to encrypt and sign your data and communication, features a versatile key management system as well as access modules for all kind of public key directories. 
+
+> In the following content, we will use GPG to refer to GnuPG tool, and PGP to refer to various concepts defined in the OepnPGP standard(e.g. PGP key, PGP key server).
+
+Key functions of GnuPG:
+
+1. Keypair(keyring) management
+2. Sign and Verify your data
+3. Encrypt and Decrypt your data
+
+Main usage scenarios of GnuPG:
+
+1. Sign or encrypt your email
+   1. Verify or decrypt the email you received
+2. Sign your git commit
+3. Manage your ssh key
+4. Encrypt your data and store it somewhere.
+
+GnuPG/OpenPGP is complex, so while using it, I have been looking forward to finding an encryption tool that is simple enough, functional enough, and widely adopted.
+
+Currently I use both age & GnuPG:
+
+1. Age for secrets encryption(ssh key & other secret files), it's simple and easy to use.
+2. GnuPG for password-store and email encryption.
+
+> At present, the safe and efficient use of GPG is probably combined with hardware keys such as yubikey. but I don't have one, so I won't talk about it here.
+
+## Practical Cryptography for Developers
+
+To use GnuGP without seamlessly, Some Practical Cryptography knowledge is required, here is dome tutorials:
+
+- English version: <https://github.com/nakov/Practical-Cryptography-for-Developers-Book>
+- Chinese version: <https://thiscute.world/tags/cryptography/>
+
+## Overview of GnuPG
+
+> GnuPG's Official User Guides: <https://www.gnupg.org/documentation/guides.html>
+
+> ArchWiki's GnuPG page: <https://wiki.archlinux.org/title/GnuPG>

+
+
+GnuPG generate every secret key separately, and encrypt them with a symmetric key derived from your passphrase.
+OpenPGP standard defines [String-to-Key (S2K)](https://datatracker.ietf.org/doc/html/rfc4880#section-3.7)
+algorithm to derive a symmetric key from your passphrase.
+
+GnuPG's [OpenPGP protocol specific options](https://gnupg.org/documentation/manuals/gnupg/OpenPGP-Options.html#OpenPGP-Options) shows that:
+
+```
+--s2k-cipher-algo name
+
+    Use name as the cipher algorithm for symmetric encryption with a passphrase if --personal-cipher-preferences and --cipher-algo are not given. The default is AES-128.
+--s2k-digest-algo name
+
+    Use name as the digest algorithm used to mangle the passphrases for symmetric encryption. The default is SHA-1.
+--s2k-mode n
+
+    Selects how passphrases for symmetric encryption are mangled. If n is 0 a plain passphrase (which is in general not recommended) will be used, a 1 adds a salt (which should not be used) to the passphrase and a 3 (the default) iterates the whole process a number of times (see --s2k-count).
+--s2k-count n
+
+    Specify how many times the passphrases mangling for symmetric encryption is repeated. This value may range between 1024 and 65011712 inclusive. The default is inquired from gpg-agent. Note that not all values in the 1024-65011712 range are legal and if an illegal value is selected, GnuPG will round up to the nearest legal value. This option is only meaningful if --s2k-mode is set to the default of 3.
+```
+
+The strongest options should be:
+
+```
+gpg --s2k-mode 3 --s2k-count 65011712 --s2k-digest-algo SHA512 --s2k-cipher-algo AES256 ...
+```
+
+To use the strongest options globally, you can specify these options in your `~/.gnupg/gpg.conf`.
+I've added them to my Home Manager's `programs.gpg.settings` option.
+
+
+### 1. PGP Key(Primary Key) generation
+
+Key management is the core of OpenPGP standard / GnuPG.
+
+GnuPG uses public-key cryptography so that users may communicate securely. In a public-key system, each user has a pair of keys consisting of a private key and a public key. **A user's private key is kept secret; it need **never be revealed. The public key may be given to anyone with whom the user wants to communicate**. GnuPG uses a somewhat more sophisticated scheme in which a user has a primary keypair and then zero or more additional subordinate keypairs. The primary and subordinate keypairs are bundled to facilitate key management and the bundle can often be considered simply as one keypair, or a keyring/keychain(which contains multiple sub key-pairs).
+
+Let's generate a keypair interactively:
+
+> Now in 2024, GnuPG 2.4.1 defaults to ECC algorithm (9) and Curve 25519 for ECC, which is morden and safe, I would recommend to use these defaults directly.
+
+```bash
+gpg --full-gen-key
+```
+
+This command will ask you for some algorithm related settings(ECC & Curve 25519), your personal info, and a strong passphrase to protect your PGP key. e.g.
+
+``` bash

+
+The generated keys are stored in `~/.gnupg` by default, the functions of each file are as follows:
+
+``` bash
+› tree ~/.gnupg/
+/Users/ryan/.gnupg/
+|-- S.gpg-agent           # socket file
+|-- S.gpg-agent.browser   # socket file
+|-- S.gpg-agent.extra     # socket file
+|-- S.gpg-agent.ssh       # socket file
+|-- S.keyboxd             # socket file
+|-- common.conf              # config file
+|-- openpgp-revocs.d         # Revocation certificates
+|   `-- F680C6D7215674ADEA421CC5E22EC419FF93EA98.rev

+|   `-- pubring.db.lock
+`-- trustdb.gpg              # a trust database
+
+4 directories, 12 files
+```
+
+The functions of most files are quite clear at a glance, but the `trustdb.gpg` in them is a bit difficult to understand. Here are the details: <https://www.gnupg.org/gph/en/manual/x334.html>
+
+Home Manager will manage all the things in `~/.gnupg/` EXCEPT `~/.gnupg/openpgp-revocs.d/` and `~/.gnupg/private-keys-v1.d/`, which is expected.
+
+### 3. Sub Key Generation & Best Practice
+
+In PGP, every keys has a **usage flag** to indicate its usage:
+
+- `C` means this key can be used to **Certify** other keys, which means this key can be used to **create/delete/revoke/modify** other keys.
+- `S` means this key can be used to **Sign** data.
+- `E` means this key can be used to **Encrypt** data. 
+- `A` means this key can be used to **Authenticate** data with various non-GnuPG programs. The key can be used as e.g. an **SSH key**.
+
+The **best practice** is:
+
+1. Generate a primary key with strong cryptography arguments(such as ECC + Curve 25519).
+2. Then generate 3 sub keys with `E`, `S` and `A` usage flag respectively.
+3. **The Primary Key is extremely important**, Backup the primary key to somewhere absolutely safe(such as two encryptd USB drivers, keep them in different places), and then **delete it from your computer immediately**.
+4. The sub key is also important, but you can generate a new one and replace it easily. You can backup it to somewhere else, and import it to another machine to use your keypair.
+5. Backup your Primary key's revocation certificate to somewhere safe, it's the last way to rescure your safety if your primary key is compromised!
+  1. It's a big problem if your revocation certificate is compromised, but not the bigest one. because it's only used to revoke your keypair, your data is still safe. But you should generate a new keypair and revoke the old one immediately.
+  1. It will be a big problem if your primary key is compromised, and you don't have a revocation certificate to revoke it. But since OpenPGP do not have a good way to distribute revocation certificate, even you have a revocation certificate, it's still hard to distribute it to others...
+
+To keep your keypair safe, you should backup your keypair according to the following steps.
+
+Now let's add the sub keys to the keypair we generated above:
+
+> `E` sub key is already generated by default, so we only need to generate `S` and `A` sub keys.
+
+> GnuPG will ask you to input your passphrase to unlock your primary key.

+Export Public Keys(Both Primary Key & Sub Keys):

+gpg --armor --export ryan4yin@linux.com > ryan4yin-gpg-keys.pub
+# check what we have exported, we should see 4 public keys
+nix run nixpkgs#pgpdump ryan4yin-gpg-keys.pub
+```
+
+Export Primary Key(The exported key is still encrypted by your passphrase):
+
+> the `!` at the end of the key ID is to force GnuPG to export only the specified key, not the subkeys.
+
+> GnuPG will ask you to input your passphrase to unlock your keypair,
+> because GnuPG need to convert the secret key's format from its internal protection format to the one specified by the OpenPGP protocol.
+
+```bash
+# replace the key ID with your own sec key's ID
+gpg --armor --export-secret-keys C8D84EBC5F82494F432ACEF042E49B284C30A0DA! > ryan4yin-primary-key.priv

+        Encrypted SHA1 hash
+...
+```
+
+As [Predictable, Passphrase-Derived PGP Keys][Predictable, Passphrase-Derived PGP Keys] says, we'll find that gpg ignored the `--s2k-count` option we specified when generating the keypair, and the `--s2k` related options we specified in `~/.gnupg/gpg.conf`, 
+the exported primary key is protectd by `SHA1` and `AES128`, which is not secure enough!
+
+So to increase the security of the exported primary key, we need to encrypt it again with a stronger algorithm, I choose `age` here(which use `scrypt` to encrypt the file key with a provided passphrase):
+
+```bash
+# for simplicity, use the same passphrase as your gpg keypair here
+age --passphrase -o ryan4yin-primary-key.priv.age ryan4yin-primary-key.priv
+rm ryan4yin-primary-key.priv
+```
+
+Export Sub Keys one by one(The exported keys is still encrypted by your passphrase):
+
+```bash
+gpg --armor --export-secret-subkeys > ryan4yin-gpg-subkeys.priv
+
+# Check the exported primary key's detail info,
+nix run nixpkgs#pgpdump ryan4yin-gpg-subkeys.priv
+
+# encrypt it again with age(scrypt)
+age --passphrase  -o ryan4yin-gpg-subkeys.priv.age ryan4yin-gpg-subkeys.priv
+rm ryan4yin-gpg-subkeys.priv
+```
+
+Your can import the exported Private Key via `gpg --import <keyfile>` to restore it, but you need to decrypt it via age first.
+
+As for Public Keys, please import your publicKeys via Home Manager's `programs.gpg.publicKeys` option, DO NOT import it manually(via `gpg --import <keyfile>`).
+
+To ensure security, delete the master key and revoke the certificate immediately after the backup is completed:
+
+```bash
+# delete the primary key and all its sub keys
+gpg --delete-secret-keys ryan4yin@linux.com
+
+# delete the revocation certificate
+rm ~/.gnupg/openpgp-revocs.d/C8D84EBC5F82494F432ACEF042E49B284C30A0DA.rev
+
+# import our subkeys back
+age --decrypt -o ryan4yin-primary-key.priv ryan4yin-primary-key.priv.age
+gpg --import ryan4yin-gpg-subkeys.priv
+```
+
+Now check the secret keys and public keys again:
+
+> A `#` at the end of the key ID means that the key is not available, because we have deleted it.
+
+```bash
+› gpg --list-secret-keys --keyid-format=long

+
+```bash
+#  Make a cleartext signature.
+gpg --clearsign <file>
+
+# Make a detached signature, with text output.
+gpg --armor --detach-sign <file>
+
+# verify the file contains a valid signature.
+gpg --verify <file>
+
+# verify the file with a detached signature.
+gpg --verify <file> <signature-file>
+```
+
+### 6. Encryption & Decryption
+
+```bash
+# Encrypt a file via recipient's public key, sign it via your private key for signing, and output cleartext.
+# so that the reciiptent can decrypt it via his/her private key.
+gpg --armor --sign --encrypt --recipient ryan4yin@linux.com <file>
+# or use this short version
+gpg -aser ryan4yin@linux.com <file>
+
+# Descrypt a file via your private key, and verify the signature via the sender's public key.
+gpg --decrypt <file>
+# or
+gpg -d <file>
+```
+
+If you just want to encrypt/decrypt a file quickly, you can use `age` with a passphrase, `gpg` can also do this, but it's not recommended(as age(scrypt)'s more secure):
+
+```bash
+# Encrypt a file via symmetric encryption(AES256), and output cleartext.
+gpg --armor --symmetric --cipher-algo AES256 <file>
+# or
+gpg -ac <file>
+
+# Decrypt a file via symmetric encryption.
+gpg --decrypt <file>
+# or
+gpg -d <file>
+```
+
+### 7. Public Key Exchange & Revocation
+
+In the case of many users, it is very difficult to exchange public keys securely and reliably with each other.
+In the Web world, There is a **Chain of Trust**** to resolve this problem:
+
+- A Certificate Authority(CA) is responsible to verify & sign all the certificate signing request.
+- Web Server can safely transmit its Web Certificate to the client via TLS protocol.
+- Client can verify the recevied Web Certificate via the CA's root certificate(which is built in Browser/OS). 
+
+But in OpenPGP:
+
+- There is key servers to distribute(exchange) public keys, but it **do not verify the identity of the key owner**, and any uploaded data is **not allowed to be deleted**. Which make it **insecure and dangerous**.
+  - Why key server is dangerous?
+    - Many PGP novices follow various tutorials to upload various key with personal privacy (such as real names) to the public key server, and then find that they can't delete them, which is very embarrassing.
+    - Anyone can upload a key to the key server, and claim that it is the key of a certain person(such as Linus), which is very insecure.
+  - **key server** is not recommend to use.
+- GnuPG will generate revocation certificate when generating keypair(`~/.gnupg/private-keys-v1.d/<Key-ID.rev>`), anyone can import this certificate to revoke the keypair. But OpenPGP standard **DO NOT provide a way to distribute this certificate to others**.
+  - Not to mention some key status query protocol like OCSP in Web PKI.
+  - Users has to pulish their revocation certificate to their blog, github profile or somewhere else, and others has to check it and run `gpg --import <revocation-certificate>` to revoke the keypair manually.
+
+In summary, **there is no good way to distribute public keys and revoke them in OpenPGP**, which is a big problem.
+
+Currently, You have to distribute your public key or revocation certificate via your blog, github profile, or somewhere else, and others has to check it and run `gpg --import` to import your public key or revocation certificate manually.
+
+Anyway, let's try to revoke a keypair:
+
+```bash
+› gpg --list-keys
+gpg: checking the trustdb
+gpg: marginals needed: 3  completes needed: 1  trust model: pgp
+gpg: depth: 0  valid:   1  signed:   0  trust: 0-, 0q, 0n, 0m, 0f, 1u

+# ......
+
+# take a look at the revocation certificate

+This is a revocation certificate for the OpenPGP key:
+
+pub   ed25519/0x55859965C2742B4B 2024-01-09 [S]
+      Key fingerprint = A2CD 07BD 9631 44CB 2725  5A6B 5585 9965 C274 2B4B
+uid                            test <test@test.t>
+
+A revocation certificate is a kind of "kill switch" to publicly
+declare that a key shall not anymore be used.  It is not possible
+to retract such a revocation certificate once it has been published.
+
+Use it to revoke this key in case of a compromise or loss of
+the secret key.  However, if the secret key is still accessible,
+it is better to generate a new revocation certificate and give
+a reason for the revocation.  For details see the description of
+of the gpg command "--generate-revocation" in the GnuPG manual.
+
+To avoid an accidental use of this file, a colon has been inserted
+before the 5 dashes below.  Remove this colon with a text editor
+before importing and publishing this revocation certificate.
+
+:-----BEGIN PGP PUBLIC KEY BLOCK-----
+Comment: This is a revocation certificate

+STuJCp+gru6OtbTCu8Y2LugQeDh7UicM7Ak=
+=Xfs6
+-----END PGP PUBLIC KEY BLOCK-----
+```
+
+As the revocation certificate says, we need to remove the first colon(`:`) before the 5 dashes(`-----BEGIN PGP PUBLIC KEY BLOCK-----`), then import it:
+
+```bash
+› gpg --import gpg-test-revoke.rev
+gpg: key 0x55859965C2742B4B: "test <test@test.t>" revocation certificate imported

+
+## How to change the gpg key of the pass password store?
+
+To ensure security, we should change the GPG key every two or three years. Here is how to do this.
+
+1. Create a new GPG key pair and backup it to a safe place.
+2. Ensure you can access both the old and new GPG keys.
+3. Update `./default.nix` to use the new GPG sub keys.
+4. Check which Key `pass` currently uses:
+
+    ```bash
+    cd ~/.local/share/password-store/
+    # check which key is used by pass
+    cat .gpg-id
+    # check which key is really used to encrypt the password
+    gpg --list-packets path/to/any/password.gpg
+    ```
+4. Change the key used by `pass`:
+    ```bash
+    # change the key used by pass, see `man pass` for more details
+    # you will be asked to enter the password of both the new and old keys
+    # then pass will re-encrypt all the passwords with the new key
+    pass init <new-key-id>
+    ```
+5. Check if the key is changed:
+    ```bash
+    # check which key is used by pass
+    cat .gpg-id
+    # check which key is really used to encrypt the password
+    gpg --list-packets path/to/any/password.gpg
+    ```
+6. Delete the old GPG key pair:
+    ```bash
+    # delete the old key pair
+    gpg --delete-secret-keys <old-key-id>
+    gpg --delete-keys <old-key-id>
+    ```

 # Termianl Emulators
 
-1. kitty: My main terminal emulator.
-2. wezterm: My secondary terminal emulator.
-3. alacritty: Standby terminal.
+I used to spend a lot of time on terminal emulators, to make them match my taste, 
+but now I found that it's not worth it, **Zellij can provide a user-friendly and unified user experience for all terminal emulators! without any pain**!
 
+Currently, I only use the most basic features of terminal emulators, such as true color, graphics protocol, etc.
+Other features such as tabs, scrollback buffer, select/search/copy, etc, are all provided by zellij!
+
+My current terminal emulators are:
+
+1. kitty: My main terminal emulator.
+    1. to select/copy a large mount of text, We should do some tricks via kitty's `scrollback_pager` with neovim, it's really painful: <https://github.com/kovidgoyal/kitty/issues/719>
+2. wezterm: My secondary terminal emulator.
+    1. its search ability is very basic, and it's not easy to use.
+    1. its scrollback buffer's copy mode is very like vim, which is nice, but zellij's even better, it can use neovim as its default scrollback buffer's editor without any pain!
+3. foot: a fast, lightweight and minimalistic Wayland terminal emulator.
+    1. foot only do the things a terminal emulator should do, no more, no less.
+    1. It's really suitable for tiling window manager or zellij users!

+# Zellij - A workspace lives in your terminal
+
+Zellij is a terminal workspace with batteries included.
+At its core, it is a terminal multiplexer (similar to tmux and screen), but this is merely its infrastructure layer.
+
+Zellij is very user-friendly and easy to use, with a step-by-step hint system that will help you get to know the keybindings, which is very like the Neovim or helix.
+
+> By contrast, tmux's key design is counterintuitive, there is no prompt system, and the plug-in performance is rubbish. It's really a pain to use.
+> tmux's inital release was in 2007, it's too old, I would recommend any users that do not have a experience with multiplexer to use zellij instead of tmux.
+
+## Why use zellij as the detault terminal environment?
+
+By auto start zellij on shell login, and exit the shell session on zellij exit, we can use zellij as the default terminal environment.
+
+By this way, We will only use the most basic features of the terminal emulator(kitty/alacritty/wezterm/...),
+while most of the functions of terminal are provided by zellij.
+Thus we can easily switch to any terminal emulator without losing any key functions,
+and do not need to take care of the differences between different terminal emulators.
+
+And Zellij can be used not only locally, but also on any remote server, which is very convenient. Learn once and use everywhere!
+
+> Yeah, you didn't misread it, zellij is very suitable for not only remotely, but also locally!
+
+Some features such as search/copy/scrollback in different terminal emulators are implemented in different ways, and has different user experience.
+For example, Wezterm's default search function is very basic, and it's not easy to use. Kitty's scrollback search/copy is really tricky to use.
+As for some Editor such as Neovim, its intergrated terminal is really useful, but zellij is more powerful and useful than it, and more stable!
+Zellij overcomes these problems, and provides a unified user experience for all terminal emulators!
+
+Teminal emulators should only be responsible for displaying characters.
+
+## Passthrough mode(Lock Mode)
+
+`Ctrl + g` lock the outer zellij interface, and all keys will be sent to the focused pane.
+
+It's extremely useful when you want to:
+
+1. Use zellij locally for daily work, and use a remote zellij via ssh to do some work on the remote server.
+1. To avoid the key conflicts between zellij and the program running in the terminal, such as vim, tmux, etc.

There're other user-specific systemd servcies, such gammastep, wallpaper-switcher, etc. which can be easily managed by Home Manager, but if we start i3/hyprland in NixOS Module, they may failed to start automatically.

+3. `base`: all common configurations for all desktops.
+4. `hyprland`: Hyprland's configuration.
+5. `i3`: i3's configuration.
+
+
+## Why install I3/Hyprland in Home Manager instead of a NixOS Module?
+
+1. I3 & Hyprland's configuration file is located in `~/.config`, which can be easily managed by Home Manager.
+2. There're other user-specific systemd servcies, such gammastep, wallpaper-switcher, etc. which can be easily managed by Home Manager, but if we start i3/hyprland in NixOS Module, they may failed to start automatically. With i3/hyprland installed via home-manager, we can control their systemd service's dependent order, to avoid issues like this.
+3. By install as less as possible in NixOS Module, we can:
+    1. Make the NixOS system more secure and stable.
+    2. Make this flake more portable to other non-NixOS systems, as home-manager can be installed on any Linux system.
