Package request: ocspd
The OpenCA OCSPD project is aimed to develop a robust and easy-to-install OCSP daemon. The server is developed as a stand-alone application and can be integrated into many different PKI solutions as it does not depend on specific database scheme. Furthermore it can be used as a responder for multiple CAs.
