Recent OpenSSL comes with SHA3. Now that Python is going to drop support for old OpenSSL, we can consider to use OpenSSL's SHA3 and drop the reference implementation from Python. For variable length SHAKE API, OpenSSL added EVP_MD_CTRL_XOF_LEN and EVP_DigestFinalXOF(). |

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

LibreSSL does neither include SHA3/SHAKE family nor Blake2. Feature requests have been open for 1.5 to almost four years. The first reply on each feature request don't come as a surprise to me... https://github.com/libressl-portable/portable/issues/199 https://github.com/libressl-portable/portable/issues/455 |
