- Serpent reference implementations (in C, Python and Ada),
- Serpent Test Values,
- Key length: 128, 192 or 256 bits; default 128 bits.
- Block size: 16 bytes.
Comment:
The original C reference code uses an unconventional byte order when printing test vectors (the order of bytes is reversed across the whole block). The correct byte order is that defined by the Java reference implementation, and by the NIST test vectors referenced above.
Patent status:
A patent has been applied for on Serpent (see references). Serpent is now completely in the public domain, and we impose no restrictions on its use. This was announced on the 21st August 1998 at the AES conference. |
