The symmetric algorithm decipher callable service deciphers data with the AES algorithm. Data is deciphered that has been enciphered in either CBC mode or ECB mode.

You can specify that the clear text data was padded before encryption using the method described in the PKCS standards. In this case, the callable service will remove the padding bytes and return the unpaded clear text data. PKCS padding is described in PKCS Padding Method.

The callable service names for AMODE(64) invocation are CSNESAD and CSNESAD1.
