Guys,
I�m facing some problems to integrate my
Java app with the PHP web interface. The problem is with cryptogrphy. The PHP side encrypts the data using a 32 bytes public key AND A 32 BYTES IV. In the Java side, I try to decrypt the data using a 32 bytes IV and I get the following exception:
java.security.InvalidAlgorithmParameterException: IV must be 16 bytes long.
If I change the IV to 16 bytes it works.
Has anybody already worked with AES 256 before and can help me?!
Thanks,
Marcelo.
