2013-12-11Revert change to sha256: ramdisks don't build with this and the obviousPhilip Guenther
2013-12-11update a few RC4 references to ChaCha. thanks sthenTed Unangst
2013-12-11md5 smells bad. switch to sha256. ok deraadt matthew mikebTed Unangst

2011-07-06Add a new kqfilter for random which returns ARC4_MAIN_MAX_BYTES for readNicholas Marriott
2011-01-11bring back carrying over state from the previous RC4 instance whenDamien Miller
2011-01-11all the bzeros in rnd are important, use explicit_bzeroTed Unangst
2011-01-10update the documentation regarding the *4 vs *6 decision for early RC4Theo de Raadt
2011-01-10move comment block regarding ARC4_MAIN_MAX_BYTESTheo de Raadt
2011-01-10randomread does its own rekeying now, so we don't need the large buf function.Ted Unangst
2011-01-10OK, this is getting silly, but we might as well zero the entropy bufferTheo de Raadt
2011-01-10zero another intermediate key storage areaTheo de Raadt
2011-01-09be more careful with nanotime() calls in early entropy storage, sinceTheo de Raadt
2011-01-08split randomattach into random_init() and random_start(), so that weTheo de Raadt
2011-01-08spacesTheo de Raadt
2011-01-08switch back from PAGE_SIZE for the sake of sparcTheo de Raadt
2011-01-08destatic. ok deraadtTed Unangst
2011-01-07some minor improvements to rnd.Ted Unangst
2011-01-07substantial rewrite. put a very thin mutex at the entropy-collectionTheo de Raadt
2011-01-07since randomwrite() also has no blocking operations at all, we need toTheo de Raadt
2011-01-06For very large operations in randomread(), use a local rc4 instanceTheo de Raadt
2011-01-06make all /dev/*random nodes respond; in fact, don't even worry aboutTheo de Raadt
2011-01-04in arc4_stir() only grab 64 bytes from the MD5 output. Grabbing moreTheo de Raadt
2011-01-01Do not fold the MD5 in half. This might have made sense to someone whenTheo de Raadt
2011-01-01comment cleanupTheo de Raadt
2010-12-31make randomattach do the parts of it's job in the right order, then moveTheo de Raadt
2010-12-31cleanup the ioctl functionTheo de Raadt
2010-12-31delete includes we do not needTheo de Raadt
2010-12-31further improvements describing what we are doingTheo de Raadt
2010-12-31all random nodes have been arc4-based for a while, so none of them everTheo de Raadt
2010-12-30be more cynical about boot-time entropy, and fold time and entropy data in.Theo de Raadt
2010-12-29knfTheo de Raadt
2010-12-29Since there is only one random_state, we can access it directly withoutTheo de Raadt
2010-12-29arc4random_count is not used; other things inside rndstats do the accountingTheo de Raadt
2010-12-29the rnd_debug stuff was not usefulTheo de Raadt
