Issue #13681 has been reported by rinzler (Colton Jenkins).

----------------------------------------
Feature #13681: Ruby digest init fails in FIPS mode when built against OpenSSL ~> 1.0.1
https://bugs.ruby-lang.org/issues/13681

* Author: rinzler (Colton Jenkins)
* Status: Open
* Priority: Normal
* Assignee: 
* Target version: 
----------------------------------------
When FIPS (https://en.wikipedia.org/wiki/FIPS_140-2) is enabled attempting to initialize any digest will kill the process due to https://github.com/openssl/openssl/commit/65300dcfb04bae643ea7b8f42ff8c8f1b1210a9e

Example,

~~~
> require 'digest'
> Digest::MD5.new
md5_dgst.c(75): OpenSSL internal error, assertion failed: Low level API call to digest MD5 forbidden in FIPS mode!

> require 'digest'
> Digest::SHA1.new
sha_locl.h(128): OpenSSL internal error, assertion failed: Low level API call to digest SHA1 forbidden in FIPS mode!
~~~

This patch will redefine alg##_Init to use the EVP interface. This allows the digest initialization to never die, but will fail when using a non FIPS algorithm (MD5).

Example,

~~~
irb(main):002:0> Digest::MD5.new
RuntimeError: disabled for fips
	from (irb):2:in `new'
	from (irb):2
	from /usr/local/bin/irb:11:in `<main>'
irb(main):003:0> Digest::SHA1.new
=> #<Digest::SHA1: da39a3ee5e6b4b0d3255bfef95601890afd80709>
~~~
