'''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>
