A python tool which decrypts perl files that have been obfuscated with Filter::Netcrypt. I have no idea who wrote Filter::Netcrypt, or who uses it, but I had the need to read something that had been Netcrypted, so I reverse engineered the thing that made them, and wrote a decrypt0r.
It was fun.
You'll still need to know the password, or have the patience to bruteforce 76 bits of keyspace. If you've got something that already knows how to en- or de-crypt the files you've got, then you'll need to instrument it to find it's password, wont you? If you don't have access to a bit of code that knows the key, then a single known plaintext ought to be enough to break it, according to my local cryptographer
There's a bunch of notes in the comments at the top about how Filter::Netcrypt works, if you care.
