Nyan

----

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.

## authenticode

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.

## makecat

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.

## stampinf

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.
