# Padding Schemes:
# 0 = (RFC2630) Each padding byte is the pad count (16 extra added if size is already a multiple of 16)
# 1 = Random bytes except the last is the pad count (16 extra added if size is already multiple of 16)
# 2 = Pad with random data. (If already a multiple of 16, no padding is added).
# 3 = Pad with NULLs. (If already a multiple of 16, no padding is added).
# 4 = Pad with SPACE chars(0x20). (If already a multiple of 16, no padding is added).
    
# To match the test vector output, we need to pad with NULL bytes.
