Stephen Heumann	4ffd064204	Add comments and copyright notices.	2017-06-27 23:30:58 -05:00
Stephen Heumann	e46264f0c4	Small decryption optimization, saving a value in a register between rounds.	2017-06-27 22:35:57 -05:00
Stephen Heumann	634ff1e865	Optimize decryption code. ... AddRoundKey is integrated into InvMixColumn and InvFinalRoundStep, rather than being done separately.	2017-06-27 20:44:14 -05:00
Stephen Heumann	a522ab6d88	Optimize decryption a bit.	2017-06-27 19:24:06 -05:00
Stephen Heumann	46fcb3badc	Add support for AES-256 decryption.	2017-06-27 18:35:04 -05:00
Stephen Heumann	0e3e511ba8	Add basic decryption implementation for AES-128 and AES-192.	2017-06-27 18:17:00 -05:00
Stephen Heumann	4314644e75	Update to also support AES-192 and AES-256.	2017-06-27 01:36:56 -05:00
Stephen Heumann	f04000c83d	Save a few cycles by not reloading the last written byte between rounds.	2017-06-26 21:49:16 -05:00
Stephen Heumann	75aac0daa9	Save a couple values on the stack rather than looking them up again. ... This is cycle-neutral (assuming a page-aligned DP), but it reduces instruction bytes and therefore may give a speedup on accelerators with caches.	2017-06-26 21:13:25 -05:00
Stephen Heumann	301021e75e	Cut out a few instructions by reusing subexpressions in registers.	2017-06-26 20:53:17 -05:00
Stephen Heumann	3df0080371	Initial working implementation of AES-128 encryption.	2017-06-26 20:41:44 -05:00
