\b The type of the key. Currently, this can be \c{ssh1} (an RSA key
for use with the SSH-1 protocol), \c{ssh-rsa} (an RSA key for use
with the SSH-2 protocol), \c{ssh-dss} (a DSA key for use with
-the SSH-2 protocol), or \c{ecdsa-sha2-*} (an ECDSA key for use with
+the SSH-2 protocol), \c{ecdsa-sha2-*} (an ECDSA key for use with
+the SSH-2 protocol), or \c{ssh-ed25519} (an Ed25519 key for use with
the SSH-2 protocol).
\b The size (in bits) of the key.
