I am trying to implement a SOAP service which will be called by a C# client and will be passed an AES-encrypted string. However, I’m running into considerable difficulty with this and I’m hoping I can find a Perl and C# guru who can help me out.

I want to start out by saying I’m not very experienced with cryptography, so that is no doubt making this more difficult.

On the Perl side, I’m using Crypt::CBC and Crypt::Rijndael. This works fine when Perl is providing data to Perl, but Crypt::CBC expects an 8-byte initialization vector, while C# requires one that is 16-byte and I don’t know how to work around this. I imagine there are other problems as well, but I’ve got to get past this one first.

Any help would be greatly appreciated.
