Rijndael[Table of Contents]
Rijndael was chosen by the cryptographic community and the United States government as the AES on December 6 2001.
- Joan Daemen and Vincent Rijmen
It was a finalist in the AES competition. The winner, Rijndael, got 86 votes at the last AES conference while Serpent got 59 votes, TwoFish 31 votes, and the other two candidates 36 votes.
Rijndael cipher documentation:
The Rijndael algorithm supports 128, 192, and 256 bit key lengths as well as 128, 192 and 256 bit block lengths. The AES on the other hand only supports 128bit block sizes.
John Savard has provided the following illustration of the primitive Rijndael operation.
Many other block ciphers possessing acceptable cryptographic strength exist
