Looks like that got me past the IV problem, but I still can't get a clean decryption of the AES output from C#. I'm starting to wonder if Crypt::CBC is just plain broken for Crypt::Rijndael. I ran the C# code that Thelonius provided and then passed the generated string back through Crypt::CBC with the correct IV set and it still didn't decrypt properly.

While I'd have to implement padding and IV extraction by hand if I don't use the module (which is not ideal) I don't know what else to do if the module won't do it properly.

Found the error; Thelonius was using the key literally to encrypt his data, while I was using a hash of the key to decrypt it. When I told Crypt::CBC to use the key literally, it worked!
