Greetings Monks!

Forgive me as I attempt, once again, to waste your time. This is more a general crypto question than a perl question, but any implementation I create will be in perl, so be merciful.

I have a password keeper program that keeps the passwords in a proprietary text file format, encrypted with AES128 and I know the password. I can open and close it with the afore-mentioned program, but I want to be able to decrypt and re-encrypt it outside of that app, so I can automate some of the tedious stuff.

I figure, if I know the password, it should be easy, right? Except, I have no idea where to start. I've googled around and all I get is pages telling me how to reset the admin password on Windows...

Anyone have any ideas?

Update:I've tried running it through gpg, but it's not in a gpg format. That's the thing. You'd think, if you know the algo and the password, it would be easy. What if the application makers put a salt on my password? What if they put the encrypted data inside a padding of their own design? There are all kind of things they could do to make it difficult for a layman like myself to decrypt, but still easy for the guys at the NSA. I'm trying to figure out how the guys at the NSA would do it.

Thanks!
