 '''BLAKE2''' is a cryptographic hash function based on BLAKE, created by Jean-Philippe Aumasson, Samuel Neves, [[Zooko Wilcox-O'Hearn]], and Christian Winnerlein. The design goal was to replace the widely used, but broken, [[MD5]] and [[SHA-1]] algorithms in applications requiring high performance in software. BLAKE2 was announced on December 21, 2012.<ref>{{cite web|url=http://lists.randombit.net/pipermail/cryptography/2012-December/003562.html|title=introducing BLAKE2 – an alternative to SHA-3, SHA-2 and MD5|first=Zooko|last=O'Whielacronx|date=21 December 2012}}</ref> A [[reference implementation]] is available under [[CC0]], the [[OpenSSL license#License incompatibilities|OpenSSL License]], and the [[Apache_License#Version_2.0|Apache Public License 2.0]].<ref name="blake2.net" /><ref name="reference-implementation-repo">{{cite web|url=https://github.com/BLAKE2/BLAKE2|title=BLAKE2 official implementations|accessdate=7 July 2019}}</ref>

 BLAKE2 removes addition of constants to message words from BLAKE round function, changes two rotation constants, simplifies padding, adds parameter block that is XOR'ed with initialization vectors, and reduces the number of rounds from 16 to 12 for '''BLAKE2b''' (successor of BLAKE-512), and from 14 to 10 for '''BLAKE2s''' (successor of BLAKE-256).
