Draft: Add Eddsa signature validation algorithms. fix #2426

Add Eddsa signature validation algorithms. fix #2426

Add in EdDSA almost everywhere. Still missing:

• Code to actually verify EdDSA algorithm along with the generation of the EdDSASecurity key class.

At this point, I'm looking for encouragement to continue this PR.

Thanks,
Warren

@wparad we are discussing this internally.
Will have an answer soon.

[brentschmaltz]

We need to see test cases for all the additional algorithms.
It would be best to create a new file for theses tests.

@brentschmaltz Not just the unit tests, the code for the implementation is missing. Can you give me some pointers on where to write that implementation. It's very hard to understand a lot of the nomenclature that is being used here.

Thanks!
