Data Field
If there is additional data associated with the application message, it is contained in this field.
The length of this field is equal to the length of the message minus the length of the message
header.
When encrypted, the data field must be padded at the end so that its length is a multiple of 8
bytes. Any pad character can be used for padding because the padding is discarded after
decryption. The data field is encrypted using triple DES (TDEA) and the cipher-block chaining
(CBC) mode with an initialization vector (IV) set to all zeros. Triple DES is used for 16-byte
keys. Single DES is used for 8-byte keys.
