For the purpose of ssh using public key authentication,
DSA-2048 keypair has been generated using openssl and both are stored locally in PEM format. Now, for configuring in the server side (authorized_keys), public key has to be in the RFC-4716 format.
Usually as a practice, for getting this key, ssh-keygen is typically used with options as,
ssh-keygen -y -f private_key.pem
which returns the corresponding public key(RFC-4716) that has to be configured in the server side.
Without ssh-keygen, Is there a possibility in openssl itself to generate the RFC-4716 specific public key from the openssl generated public (or) private key?
