Public key in the PEM textual encoding: the Base64 of a DER SubjectPublicKeyInfo structure (RFC 5280) between -----BEGIN PUBLIC KEY----- and -----END PUBLIC KEY----- (RFC 7468, section 13). OpenSSL also writes RSA keys in the PKCS #1 form with the label RSA PUBLIC KEY. A public key is not secret; for the private key see x509_private_key.
