            When running on a FIPS enabled host, puppet will change the default values for digest_algorithm and supported_checksum_types to use SHA256 instead of MD5, as the latter is not FIPS compliant. Puppet will also emit errors and gracefully exit if configured to use MD5 algorithms.

            Description

            Puppet 5.4.0:
            N/A:
            Redhat7- FIPS mode:

            FIPS mode prohibits use of certain algorithms e.g. MD5 (as applicable to puppet currently) and any attempt to use them results in abrupt program termination or abort. While customers using Puppet agents on FIPS mode platforms should be aware of such limitations there might be un-intentional usages which will result in user un-friendly errors.
            We need to intercept any such prohibited usages at runtime and provide graceful error messages.
            Create a manifest with a file resource while setting its checksum attribute to md5 and attempt applying it on agent in fips mode.

            Expected: Provide a graceful error while disallowing the operation.

            Actual: Error "md5_dgst.c(82): OpenSSL internal error, assertion failed: Digest MD5 forbidden in FIPS mode!
            Aborted"
