Hello!

I created a key for my netbox user to be able to use secrets. The key is inactive.

When I try to activate the key from the admin panel with my own user I receive an error (debug below) . If I try to activate using the admin user the message You do not have an active User Key. appears on the top of the page without any debug error.

Netbox v1.3.0.

Could you provide the traceback as well please? That will help me figure out where the error is occurring.

I need to add some error handling there, but it looks like the private key provided is invalid. Are you able to decrypt secrets using the private key?

When I try to unlock a secret, the private key is requested. The Unlock button changes to Lock and no error is throw, but the secret remains a secret (sequence of asterisks).
Only the user that has created the user key in earlier release is has the status as active. The user key was probably create using v1.2.1 or v1.2.2 (14 july). All others users have the user key status as inactive.

It sounds like the private RSA key you've provided isn't valid. Are you sure you're using the correct key? If so, try deleting all secrets and userkeys and starting over.

We need to improve error reporting when an invalid key is used.

I already tried to delete the keys and add a new one generated by netbox. I also tried to use a key pair created out of netbox and the same happens.

I also tried to use the key pair from the user that has the key status as active. No success...

This happened on my instance as well. However I was able to fix it by purging the database and then only using keys provided by netbox rather than my own RSA key. I don't know if that helps to reach a solution but it should at least help augustocarlson

@jpanos do you mean purging all data from the userkey table? or the entire database?

@augustocarlson I purged and repopulated entire database because it got to a point where my main userkey wasn't working which meant that I could no longer access my secrets or activate others keys.

@jeremystretch Yes. I just did a full new install. The first user to create an user key, the key is activated just after the creation. The others users have the key set as inactive after the creation. When trying to activate, the error is throw.

Could you please describe exactly what you're doing? I don't encounter any problem doing the following on v1.3.2.

  1. Log in as the superuser created during install (admin).
  2. Go to admin's profile page and create a user key. Generate an RSA key pair from NetBox and save the private key.
  3. Admin now has an active user key.
  4. Create a second user (bob) via the admin UI.
  5. Log in as bob in a separate browser session.
  6. Go to bob's profile page and create a user key. Generate an RSA key pair from NetBox just as I did with admin. Bob now has an inactive user key.
  7. As admin, select bob's private key from the list in the admin UI and select "activate selected user keys" from the dropdown menu.
  8. Ensure that user bob is selected and paste admin's private RSA key into the box labeled "your private key" and click activate. Bob's user key is now active.

@jeremystretch It worked. It was a problem with the incorrect key during a copy/paste. I was able to replicate the same mistake when I did the new install. Shame on me! Thank you for your support and patience.
