def initialize(options)
    if options.has_key?(:copy_nonce)

Instance Method Details

- (OpenSSL::OCSP::BasicResponse) create_basic_response(request, statuses)

It is UNWISE to call this method directly because it assumes that the request is validated. You probably want to take a look at R509::Ocsp::Signer#handle_request

Parameters:

  • request (OpenSSL::OCSP::Request)
  • statuses (Hash) —

    hash from R509::Ocsp::Helper::RequestChecker#check_statuses

Returns:

  • (OpenSSL::OCSP::BasicResponse)

        #revocation time is retarded and is relative to now, so
        #let's figure out what that is.
        if status[:status] == OpenSSL::OCSP::V_CERTSTATUS_REVOKED
            revocation_time = status[:revocation_time].to_i - Time.now.to_i
        end

                                status[:status],
                                status[:revocation_reason],
                                revocation_time,

                                )
    end

    #this method assumes the request data is validated by validate_request so all configs will be the same and
    #we can choose to use the first one safely
    config = statuses[0][:config]

    #confusing, but R509::Cert contains R509::PrivateKey under #key. PrivateKey#key gives the OpenSSL object
    #turns out BasicResponse#sign can take up to 4 params
    #cert, key, array of OpenSSL::X509::Certificates, flags (not sure what the enumeration of those are)
    basic_response.sign(config.ocsp_cert.cert,config.ocsp_cert.key.key,config.ocsp_chain)
end

- (OpenSSL::OCSP::OCSPResponse) create_response(response_status, basic_response = nil)

Builds final response.

generated by create_basic_response

Parameters:

  • response_status (OpenSSL::OCSP::RESPONSE_STATUS_*) —

    the primary response status

  • basic_response (OpenSSL::OCSP::BasicResponse) (defaults to: nil) —

    an optional basic response object

Returns:

  • (OpenSSL::OCSP::OCSPResponse)
