[3.12] gh-118224: Load default OpenSSL provider for nonsecurity algorithms (GH-118236) by xnox · Pull Request #118238 · python/cpython

… algorithms

When OpenSSL is configured to only load "base+fips" providers into the
Null library context, md5 might not be available at all. In such cases
currently CPython fallsback to internal hashlib implementation is
there is one - as there might not be if one compiles python with
--with-builtin-hashlib-hashes=blake2. With this change "default"
provider is attempted to be loaded to access nonsecurity hashes.
