Instance Method Details

#create_basic_response(request, statuses) ⇒ OpenSSL::OCSP::BasicResponse

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)

def create_basic_response(request,statuses)
  basic_response = OpenSSL::OCSP::BasicResponse.new

  basic_response.copy_nonce(request) if @copy_nonce

  statuses.each do |status|
    #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
    basic_response.add_status(status[:certid],
                status[:status],
                status[:revocation_reason],
                revocation_time,
                -1*status[:config].ocsp_start_skew_seconds,
                status[:config].ocsp_validity_hours*3600,
                [] #array of OpenSSL::X509::Extensions
                )
  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

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

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)
