Failure to create and verify ECDSA signatures

[aleksandrs-ledovskis]

Haven't tested it with other algorithms, but attempting to generate a Digest-type signature using secp256r1/P-256 (ECDSA) key using SHA-1 hashing algorithm

OpenSSL::PKey::EC.new(File.read('ecdsa.key')).sign(OpenSSL::Digest::SHA1.new, 'foobar')

fails with

OpenSSL::PKey::PKeyError: SHA1WITHEC Signature not available
    sign at org/jruby/ext/openssl/PKey.java:223

---

Cursory investigation brings me to Bouncy Castle, where SHA1WITHECDSA algo does exists.

I have cobbled up a hacky patch to pass ECDSA in around here when PKeyEC instance is in play. It does work (both sign/verify output proper values, cross checked with CRuby's OpenSSL), but am not sure about architectural validity of this approach.

Hey Aleks, that makes sense. The EC support wasn't completely polished.
But this part should return "ECDSA" ... as you already figured. Please fire up a PR.

@kares As the 25972fd commit only contains test but not an implementation, and causes some CI failures, I think this issue in itself isn't fully resolved?
