-----END CERTIFICATE-----

As you may have noticed, the certificate contains essential elements:
  • the issuer
  • the owner/subject
  • the public key of the owner
  • the dates of validity of this certificate
  • the signature of the certificate to ensure this certificate hasn't been tampered with.

    The certificate does not contain the private key as it should never be transmitted in any form whatsoever.

    No for most cases, but maybe yes if the certificate is in form of .PEM, .pfx or .P12.
