KEYS: Allow authentication data to be stored in an asymmetric key
Allow authentication data to be stored in an asymmetric key in the 4th element of the key payload and provide a way for it to be destroyed. For the public key subtype, this will be a public_key_signature struct. Signed-off-by: David Howells <dhowells@redhat.com>
