considered sufficient. DSA keys must be exactly 1024
bits as specified by FIPS 186-6. For ECDSA keys, the
'num-bits' value determines the key length by selecting
from one of three elliptic curve sizes: 256, 384 or
521 bits. Attempting to use bit lengths other than
these three values for ECDSA keys will fail. ECDSA-SK,
Ed25519 and Ed25519-SK keys have a fixed length and
thus the 'num-bits' value is not specified.";
