The OpenSSL engine of Digest uses the low-level API of OpenSSL, whose
use has been discouraged for years for multiple reasons.
A long-standing issue on a FIPS-enabled system is that using ::Digest
results in crashing the Ruby process, because the low-level API lacks
the mechanism to report an error (the policy violation) and thus kills
the process as a last resort[1][2]. Also, the upcoming OpenSSL 3.0 will
deprecate it for future removal[3]. Compiling with
-Wdeprecated-declarations will start to emit warnings.
A proper fix for this is to make it use the EVP API instead. This is a
non-trivial work as it requires backwards-incompatible changes to the
framework interface of Digest::Base and rb_digest_metadata_t.
It is more than 15 years ago that the openssl library became part of the
standard library. It has implemented the exactly same functionality as
OpenSSL::Digest, in fact, as a subclass of Digest::Class. There is not
much point in having an identical code in the digest library. Let's
just get rid of OpenSSL within digest. This leaves the C implementations
and the CommonCrypto engine for Apple systems.
A patch is being prepared for the openssl library to provide ::Digest
constants for better performance[4].
