Q: 

Decryptionproblem iPhone

Hey

i have some problem to decrypted a file, which was encrypted using a C# AES256 implementation with an IV (in vector) as an 16bit byte-array and 32bit byte-array for the key. For decryption i used Apple's CommonCryptor CCCrypt, but my key is an NSString. So how can i convert the NSString to an 32bit byte-array/unsigned char?
