Block ciphers list

Cipher name (used in algorithm)	State	NumRounds	Block-size Bytes	Key-size Bytes	Note	Licence	Code source
AES	working	10	16	16		no	implementation
BLOWFISH	working	16	8	4-56		no	implementation, test vectors
MARS	working	0-16 (8 always used)	16	16, 24, 32		no	implementation, test vectors
RC6	working	0-20	16	16, 24, 32		no	implementation, test vectors
SERPENT	working	0-32	16	16, 24, 32		no	implementation, test vectors
TWOFISH	working	0-16	16	16, 24, 32		no	implementation, test vectors
SIMON	working	0-(32-72)	4-16	8-32	parametrization	no	implementation
SPECK	working	0-(22-34)	4-16	8-32	parametrization	no	implementation
GOST	working	32	8	32		no	implementation, test vectors
SINGLE-DES	working	16	8	7	basic DES, 7 B of key are expanded to 8 B of input	no	implementation, test vectors
TRIPLE-DES	working	16	8	21	3-DES, 21 B expanded to 24 B	no	implementation, test vectors
TEA	working	32	8	16		no	implementation, test vectors
RC4	working	not round-reduced	does not operate on blocks	5–256	It is not block cipher, but it is well-known, therefore it is here. Can be weakened by selection of weak positions.	no	implementation, test vectors
