Lookup ciphers programatically.

My advice would be to avoid specific support for any particular
digest algorithm. Instead, provide bindings to:

• EVP_get_digestbyname(),
• EVP_MD_CTX_create(3),
• EVP_DigestInit_ex(3),
• EVP_DigestUpdate(3),
• EVP_DigestFinal_ex(3),
• EVP_MD_CTX_destroy(3)

which can they use any available digest algorithm (by name).

• EVP_get_digestbyname(),

This is what OpenSSL::Digest.new("digest-algo-name") currently does.

I agree with this idea in general. It's hard to maintain those constants for specific algorithms (as in lib/openssl/digest.rb) up to date, and I also think we should be agnostic on the algorithms.

The same goes for OpenSSL::Cipher.

I think this can be closed now #362 is merged?

Yes, thanks for your work!
