Stream Ciphers
|
ARC4 |
ARC4 (Alleged RC4) is a stream cipher compatible with (i.e. is
the same as) RSA's RC4.
ARC4 has a key size of up to 2,048 bits. This algorithm was
first presented to the public September 10, 1994 by an anonymous
Cypherpunk and confirmed the claim. ARC4 is present in most
secure web browses. |

ISAAC |
Fairly unknown algorithm created by Bob
Jenkins. 32-bit block size, 8295 bit keysize. |
Block Ciphers
AES
(Rijndael) |
Advance Encryption
Standard (AES) is the new US government encryption standard.
Released as Rijndael
before winning rank as AES. Block size is variable from 128,
192 and 256 bits as is keysize. Created by Joan Daemen and
Vincent Rijmen. |
|
RC5 |
RC5
is 32, 64 or 128-bit block size, 2040-bit key size. Created
by Ronald L. Rivest and RSA
Not seen too much as it was prity much replaced with RC6. |
|
RC6 |
An AES candidate eliminated the last round. Created by Ronald
L. Rivest and RSA. 128-bit block size and up to 2048 bits
of keyspace. Actually one of my preferred block ciphers because
of it's clean design. |
|
CAST-256 |
Cast-256 block sizes of
128 bits. Keysize up to 256 bits. C. Adams and J. Gilchrist
of Entrust Technologies. |
|
Blowfish |
Block size of 64-bits, keysize of up to 448 bits. Created
by Bruce Schneier of Counterpane
as a replacement for DES. Algorithm appeared in the book "Applied
Cryptography" and got a great deal of attention because of it. |
