In Fedora Rawhide, there was disable support for verification of certificate, CRL, and OCSP signatures using MD5 in OpenSSL [1, 2], therefore I observe following test errors:

   7) Error:
 test_sign_and_verify(OpenSSL::TestX509Request):
 OpenSSL::X509::RequestError: unknown message digest algorithm
     /builddir/build/BUILD/ruby-2.0.0-p247/test/openssl/test_x509req.rb:111:in `verify'
     /builddir/build/BUILD/ruby-2.0.0-p247/test/openssl/test_x509req.rb:111:in `test_sign_and_verify'
   8) Error:
 test_sign_and_verify(OpenSSL::TestX509Certificate):
 OpenSSL::X509::CertificateError: unknown message digest algorithm
     /builddir/build/BUILD/ruby-2.0.0-p247/test/openssl/test_x509cert.rb:140:in `verify'
     /builddir/build/BUILD/ruby-2.0.0-p247/test/openssl/test_x509cert.rb:140:in `test_sign_and_verify'
 
I was suggested by OpenSSL maintainer, that MD5 is obsolete and for modernization, it would be more useful to test SHA256 instead of MD5 for example. Any chance to make this test could pass out of the box and support more modern hashing algorithms?
