In the software development ecosystem, a "gem" is a packaged library or application written in the Ruby programming language. A "gem file decryptor" in this context is a tool designed to decrypt and reveal the contents of these encrypted Ruby packages.
Some gems (e.g., using ruby2c or mjit ) may distribute binary extensions. This is but requires:
