I'm looking for information about the key generated by newhostkey command. What is the format of pubkey line? It seem Base64 encoded binary but I cannot Base64 decode it. I have tried to assume it as PEM by adding  -----BEGIN PRIVATE KEY----- and -----END PRIVATE KEY----- at the first and last lines and try to do openssl rsa and openssl asn1parse to decode that public key but failed.

Best regards,
