How can I make my AES encryption identical between Java and Objective-C (iPhone)? http://stackoverflow.com/questions/2280375/how-can-i-make-my-aes-encryption-identical-between-java-and-objective-c-iphone to use something else. EDIT From here I saw an example. Seems like you need to pass the kCCOptionECBMode to CCCrypt ccStatus CCCrypt encryptOrDecrypt kCCAlgorithm3DES kCCOptionECBMode this could help vkey 123456789012345678901234 key kCCKeySize3DES..

Encrypting 16 bytes of UTF8 with SecKeyWrapper breaks (ccStatus == -4304) http://stackoverflow.com/questions/5884119/encrypting-16-bytes-of-utf8-with-seckeywrapper-breaks-ccstatus-4304 16 bytes of UTF8 with SecKeyWrapper breaks ccStatus 4304 I'm using Apple's SecKeyWrapper class from the CryptoExercise sample code in the Apple docs to do some symmetric encryption.. correctly. With 16 characters I can encrypt but on decrypt it throws an exception after the CCCryptorFinal call with ccStatus 4304 which indicates a decode error. Go figure. I understand that AES128 uses 16 bytes per encrypted block so I get the..
