This new algorithm increased the cost of password guessing attacks by several orders of magnitude. text/html 2010-12-26T21:03:12+02:00 https://openwall.info/wiki/MSCash2?rev=1293393792&do=diff MSCash2 Algorithm Description Domain cached credentials (DCC) are cached domain logon information that are stored locally in the Windows registry of Windows operating systems (cf.

However, many more had applied, and we wanted to work with some of those who we couldn't accept specifically under the GSoC program.

It builds upon Colin Percival's scrypt. This implementation is able to compute native yescrypt hashes as well as classic scrypt. Right now, this is primarily a copy of the content from the PHC wiki, but it should probably be moved to a sub-page and this page reused for links to resources related to yescrypt.
