The simplest way to verify signatures is using :func:`verify_signature`:: cert = open('certs.pem').read() valid = crypt.verify_signature(message, signature, cert) If you're going to verify many messages with the same certificate, you can use :class:`RSAVerifier`:: cert = open('certs.pem').read() verifier = crypt.RSAVerifier.from_string(cert) valid = verifier.verify(message, signature) To sign messages use :class:`RSASigner` with a private key:: private_key = open('private_key.pem').read() signer = crypt.RSASigner.from_string(private_key) signature = signer.sign(message) The code above also works for :class:`ES256Signer` and :class:`ES256Verifier`.
