Serpent
- Block length = 128 bits
- Key length = 128, 192 or 256 bits
Created in 1998 by Ross Anderson, Eli Biham and Lars Knudsen. It was a finalist in the contest of preparing a prototype of the AES cipher, where it was placed second.
Usage
The Serpent cipher is considered to be stronger but also slower than AES. It has not been patented and is in the public domain. Everybody can use it in his software without any limitations.
