WebAES is specified for 128-bit block size or 16 bytes which is also the size of the IV. AES key sizes may be 128-bit, 192-bit or 256-bit or 16 byte, 24 byte or 32 byte respectively. They can't be different from those. So use this for AES-256: byte xAESKey [32]; byte xAESIv [16]; This should have nothing to do with the mode of operation.

CommonCrypto supports both ECB and NoPadding through various flags. You don't need some third party library for that, but of course you shouldn't use that code at all. Instead you should use a library that does that for you.
