Constructor Details

#OpenSSL::OCSP::CertificateId.new(subject, issuer, digest = nil) ⇒ Object #OpenSSL::OCSP::CertificateId.new(der_string) ⇒ Object #OpenSSL::OCSP::CertificateId.new(obj) ⇒ Object

Creates a new OpenSSL::OCSP::CertificateId for the given subject and issuer X509 certificates. The digest is a digest algorithm that is used to compute the hash values. This defaults to SHA-1.

If only one argument is given, decodes it as DER representation of a certificate ID or generates certificate ID from the object that responds to the to_der method.
