[New-bugs-announce] [issue30102] improve performance of libSSL usage on hashing

[Gustavo Serra Scalet]

New submission from Gustavo Serra Scalet:

To correctly pick the best algorithm for the current architecture,
libssl needs to have OPENSSL_config(NULL) called as described on:
https://wiki.openssl.org/index.php/Libcrypto_API

This short change lead to a speedup of 50% on POWER8 when using
hashlib.sha256 digest functionality as it now uses a SIMD approach that was already existing but not used by cpython.
