Advanced Encryption Standard	SP network	128	128,192,256	10 to 14	one 8*8	US, 2002 onward	current US standard, widely used
Data Encryption Standard	Feistel	64	56	16	8 6*4	US, 1976-2002	obsolete, key too short against brute force
Blowfish	Feistel	64	up to 556	16	4 8*32, key-dependent		widely used
CAST-128	Feistel	64	40 to 128	16	4 8*32, using bent functions		widely used, including PGP
GOST	Feistel	64	256	32	8 4*4	Soviet Union
International Data Encryption Algorithm		64	128	8	none	Europe	uses modular multiplication
SAFER SK-128	SP network	64	128	8		Singapore	uses pseudo-Hadamard transformation
