From: k@... Date: 2016-10-27T07:10:17+00:00 Subject: [ruby-core:77773] [Ruby trunk Feature#12802] Add BLAKE2 support to Digest Issue #12802 has been updated by Kazuki Yamaguchi. Is there still a supported environment without 64-bit integer support? ext/digest/sha2/sha2.c is already using 64-bit integers. It is compiled only when OpenSSL (or CommonCrypto) is not available, but the current versions of OpenSSL also require uint64_t. But, I'm wondering, why not add the SHA-3 winner but only BLAKE2? ---------------------------------------- Feature #12802: Add BLAKE2 support to Digest https://bugs.ruby-lang.org/issues/12802#change-61078 * Author: Tony Arcieri * Status: Open * Priority: Normal * Assignee: ---------------------------------------- BLAKE2 is a fast, modern hash function, based on improvements to the BLAKE function, which was a SHA3 finalist. BLAKE2 performs about twice as fast in software as SHA3 winner Keccak: https://blake2.net/ BLAKE2 has received an informational RFC 7693 from the IETF: https://tools.ietf.org/html/rfc7693 It was added to the Python standard library in Python 3.6: https://docs.python.org/3.6/library/hashlib-blake2.html If there's interest in supporting BLAKE2 in the Ruby standard library, I can put together a patch. -- https://bugs.ruby-lang.org/ Unsubscribe:
