OpenSSL::OCSP::CertificateId

An OpenSSL::OCSP::CertificateId identifies a certificate to the CA so that a status check can be performed.

OpenSSL::OCSP::CertificateId.new(subject, issuer, digest = nil) → certificate_id click to toggle source

OpenSSL::OCSP::CertificateId.new(der_string) → certificate_id

Creates a new OpenSSL::OCSP::CertificateId for the given subject and issuer X509 certificates. The digest is used to compute the certificate ID and must be an OpenSSL::Digest instance.

If only one argument is given, decodes it as DER representation of a certificate ID.

}

cmp_issuer(other) → true or false click to toggle source

Compares this certificate id's issuer with other and returns true if they are the same.

 
               static VALUE

{
    OCSP_CERTID *id;
    ASN1_OCTET_STRING *name_hash;
