Thanks Ryan! I followed instructions of installing BC on their site and they didn't mention that "Java Cryptography Extension (JCE) Unlimited Strength Jurisdiction Policy" is required too. After installing it all works fine!

Ryan, could you plese elaborate how did you manage to get AES with Bouncy Castle working? I get the same error "Operation not possible (Bad input or parameters)" both with built-in JCE and BC.
