[Python-Dev] New hash algorithms: SHA3, SHAKE, BLAKE2, truncated SHA512 (original) (raw)

OpenSSL sucks. Python would only have to bundle a reference implementation of the new hash algorithm(s), and unlike TLS suites they tend to just work.

BLAKE2 is important, since it removes the last objection to replacing MD5 - speed - that has made it hard for cryptography fans to convince MD5 users to upgrade.

I know, but still don't think that's a good idea. It makes sense in case you don't want to carry around OpenSSL all the time, but how often does that happen nowadays ? BTW: If I recall correctly, those hash implementations predate the deeper support for OpenSSL we now have in Python. -- Marc-Andre Lemburg eGenix.com Professional Python Services directly from the Experts (#1, May 27 2016) >>> Python Projects, Coaching and Consulting ... http://www.egenix.com/ >>> Python Database Interfaces ... http://products.egenix.com/ >>> Plone/Zope Database Interfaces ... http://zope.egenix.com/
