Nyan is a collection of utilities to create and manipulate Microsoft's CAT and INF files.

Thanks to Matt Graeber (https://github.com/mattifestation) and Michał Trojnara (https://github.com/mtrojnar) for their reverse-engineering work, which made this whole thing a lot easier.

Prints the Authenticode hash of a PE file, in the same manner as sha1sum etc. This is a hash of the whole file except the bits relating to signing, and is the hash that gets embedded into the INF file.

Clone of the Microsoft tool makecat, used to create a CAT file from a text CDF file. See https://learn.microsoft.com/en-us/windows/win32/seccrypto/makecat for documentation.

Clone of the Microsoft tool stampinf, which updates the date and version in an INF file. See https://learn.microsoft.com/en-us/windows-hardware/drivers/devtest/stampinf for documentation.
