PBKDF2 AES 256/CBC

[hlore]

is it difficult to create a module to use with Hashcat?

Not simple, but possible.

Full sources are accessible. You can find module with similar algorithm and use it as basis. Start from this manual.

I've been trying to figure this out, but it's above my abilities.  Are there pros in this subject that I can hire to do this for me?   I'm at my wits end.
