Question:

Does AES Decryption with CypherMode CBC decrypt AES CCM?

Oct 16 '12 at 17:19

I have AES128 CCM encrypted byte data and need to decrypt it. Would setting: crypt.put_CryptAlgorithm("aes"); crypt.put_CipherMode("cbc"); crypt.put_KeyLength(128); crypt.SetEncodedKey(hexKey,"hex");

and then using crypt.DecryptBytes work? I see Counter with CBC-MAC is CCM, not sure what straight CBC is.

I'm sorry to say that at the time of this writing (16-Oct-2012) that Chilkat does not implement CCM. You won't be able to decrypt using Chilkat v9.3.2.
