Class SecurityKeyPublicKey

java.lang.Object
com.hierynomus.sshj.userauth.fido.SecurityKeyPublicKey
All Implemented Interfaces:
Serializable, Key, PublicKey
public class SecurityKeyPublicKey extends Object implements PublicKey
A public key for an OpenSSH FIDO/U2F security key, i.e. one of the sk-ecdsa-sha2-nistp256@openssh.com or sk-ssh-ed25519@openssh.com key types.

Such a key is a regular ECDSA (NIST P-256) or Ed25519 public key with an additional application string attached (typically "ssh:"). The application string is part of the SSH wire encoding of the key and is mixed into every signature the authenticator produces, so it has to travel with the key. This wrapper keeps the underlying PublicKey and the application together.

It deliberately does not implement ECKey or EdECKey so that KeyType.fromKey(java.security.Key) can tell a security-key public key apart from a plain ECDSA/Ed25519 public key.
