Remarques

A PEM-encoded X.509 SubjectPublicKeyInfo will begin with -----BEGIN PUBLIC KEY----- and end with -----END PUBLIC KEY-----, with the base64 encoded DER contents of the key between the PEM boundaries.

          The PEM is encoded according to the IETF RFC 7468 "strict"
          encoding rules.
