OpenSSL's SHA-3 implementation is a tiny bit faster than our builtin copy of SHA-3. builtin SHA-3 with PGO $ python3 -m timeit -s "from _sha3 import sha3_256; d = b'12345678' * 1000" "sha3_256(d)" 10000 loops, best of 5: 20.3 usec per loop builtin SHA-3 without PGO $ ./python -m timeit -s "from _sha3 import sha3_256; d = b'12345678' * 1000" "sha3_256(d)" 10000 loops, best of 5: 21.1 usec per loop OpenSSL SHA-3 $ ./python -m timeit -s "from _hashlib import openssl_sha3_256 as sha3_256; d = b'12345678' * 1000" "sha3_256(d)" 20000 loops, best of 5: 19.1 usec per loop OpenSSL's Blake2 implementation is also a tiny bit faster. (b.copy().update() because the _hashlib module doesn't have fast constructor yet) $ python3 -m timeit -s "from _blake2 import blake2b; b = blake2b(); d = b'12345678' * 1000" "b.copy().update(d)" 50000 loops, best of 5: 9.67 usec per loop $ python3 -m timeit -s "from _hashlib import new; b = new('blake2b512'); d = b'12345678' * 1000" "b.copy().update(d)" 50000 loops, best of 5: 8.87 usec per loop ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue37630> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
