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.

WebNever use ECB! It is insecure. I recommend an authenticated encryption mode, like EAX or GCM. If you can't use authenticated encryption, use CBC or CTR mode encryption, and then apply a MAC (e.g., AES-CMAC or SHA1-HMAC) to the resulting ciphertext.
