All Implemented Interfaces:

Signature

public class SignatureSkEd25519
extends AbstractSecurityKeySignature

Signature for the sk-ssh-ed25519@openssh.com FIDO/U2F key type. The raw Ed25519 signature is used as-is in both directions.

Method Summary

Modifier and Type	Method	Description
protected byte[]	deviceSignatureToSsh(byte[] deviceSignature)	Convert the authenticator's native signature into the SSH raw-signature encoding (r||s as two mpints for ECDSA, unchanged for Ed25519).
protected byte[]	sshSignatureToDevice(byte[] sshRawSignature)	Convert the SSH raw-signature encoding read off the wire into the byte format the JCA verification engine expects (DER for ECDSA, unchanged for Ed25519).
