Set an object which will compute an ECDSA signature. By default, ECDSA signatures are computed internally which means that the private key must be available on this machine. Requirements for string parameters: - GenerateECCKeyPair must not be set . Requirements for integer parameters: - GenerateKeyPair must not be set - SelectCertificate must be zero (which is the default value) . Requirements for blob parameters: - Certificate must not be set - CertificatePrivateKey must not be set . setRSA() and setPKCS7() must not have been called
