File Type Analyzers
====================
OWASP dependency-check contains several file type analyzers that are used
to extract identification information from the files analyzed.

| Analyzer | File Types Scanned | Analysis Method |
| -------- | ------------------ | --------------- |
| [Archive](./archive-analyzer.html) | Zip archive format (\*.zip, \*.ear, \*.war, \*.jar, \*.sar, \*.apk, \*.nupkg); Tape Archive Format (\*.tar); Gzip format (\*.gz, \*.tgz); Bzip2 format (\*.bz2, \*.tbz2) | Extracts archive contents, then scans contents with all available analyzers. |
| [Assembly](./assembly-analyzer.html) | .NET Assemblies (\*.exe, \*.dll) | Uses [GrokAssembly.exe](https://github.com/colezlaw/GrokAssembly), which requires .NET Framework or Mono runtime to be installed. |
| [Autoconf](./autoconf.html) | Autoconf project configuration files (configure, configure.in, configure.ac) | [Regex](https://en.wikipedia.org/wiki/Regular_expression) scan for AC_INIT metadata, including in generated configuration script. |
| [Central](./central-analyzer.html) | Java archive files (\*.jar) | Searches Maven Central or a configured Nexus repository for the file's SHA1 hash. |
| [CMake](./cmake.html) | CMake project files (CMakeLists.txt) and scripts (\*.cmake) | Regex scan for project initialization and version setting commands. |
| [Composer Lock](./composer-lock.html) | PHP [Composer](http://getcomposer.org) Lock files (composer.lock) | Parses PHP [Composer](http://getcomposer.org) lock files for exact versions of dependencies. | 
| [Jar](./jar-analyzer.html) | Java archive files (\*.jar); Web application archive (\*.war) | Examines archive manifest metadata, and Maven Project Object Model files (pom.xml). |
| [Nexus](./nexus-analyzer.html) | Java archive files (\*.jar) | Searches Sonatype or a configured Nexus repository for the file's SHA1 hash. In most cases, superceded by Central . |
| [Node.js](./nodejs.html) | NPM package specification files (package.json) | Parse JSON format for metadata. |
| [Nuspec](./nuspec-analyzer.html) | Nuget package specification file (\*.nuspec) | Uses XPath to parse specification XML. |
| [OpenSSL](./openssl.html) | OpenSSL Version Source Header File (opensslv.h) | Regex parse of the OPENSSL_VERSION_NUMBER macro definition. |
| [Python](./python.html) | Python source files (\*.py); Package metadata files (PKG-INFO, METADATA); Package Distribution Files (\*.whl, \*.egg, \*.zip) | Regex scan of Python source files for setuptools metadata; Parse RFC822 header format for metadata in all other artifacts. |
| [Ruby Gemspec](./ruby-gemspec.html) | Ruby makefiles (Rakefile); Ruby Gemspec files (\*.gemspec) | Regex scan Gemspec initialization blocks for metadata. |
