[RFR] 8166597: Crypto support for the EdDSA Signature Algorithm (JEP 339)

[Weijun Wang]

I was playing with keytool with your patch and noticed sun.security.util.KeyUtil.getKeySize(Key) does not support an EdECKey. While we use curve name instead of key size in EC to describe the parameters, the size is still useful in determining the strength.

There is also a KeyUtil.getKeySize(AlgorithmParameters) nearby. I'm not involved with previous discussions on EdDSA design, but why does EdDSASignature.engineGetParameters() throw an UOE?

Another small problem:

You reverted the copyright year from 2020 to an earlier year in module-info.java, keytool/Main.java.

Thanks,
Max
