Key pair validation

[stevemit]

Is there a one-liner for validating that a private and public key match?

If not, BouncyCastle could implement this utility by having org.bouncycastle.crypto.util.PrivateKeyFactory also produce the public key parameters, and having org.bouncycastle.crypto.params.AsymmetricKeyParameter implement equals().

BouncyCastle is uniquely positioned to make this common task easy.

In FIPS we have a ConsistentKeyPair class which checks for correspondence between the two when used (well as best it can). Is that the kind of thing you are looking for?
