                Definition: Byte padding for a cypher block chaining mode encryption, if the padding is not implicit.
Type: BytePadding1Code (String)
Allowed Values:
- LNGT (Length Padding): Message to encrypt is completed by a byte value containing the total number of added bytes. NUL8 Null80Padding Message to encrypt is completed by one bit of value 1, followed by null bits until the encryption block length is reached.
- NUL8
- NULG (Null Length Padding): Message to encrypt is completed by null byte values, the last byte containing the total number of added bytes.
- NULL (Null Padding): Message to encrypt is completed by null bytes.
- RAND (Random Padding): Message to encrypt is completed by random value, the last byte containing the total number of added bytes.
