OpenCA
OpenCA, officially the OpenCA PKI Research Labs and formerly the OpenCA Project, is a PKI collaborative effort to develop a robust, full-featured and Open Source out-of-the-box Certification Authority implementing the most used protocols with full-strength cryptography. OpenCA is based on many Open-Source Projects. Among these there are OpenLDAP, OpenSSL and Apache Projects.
The project development is divided into two main tasks: studying and refining the security scheme that guarantees the best model to be used in a Certification Authority and developing software to easily set up and manage a Certification Authority.
The software development side of the project is further divided into the following sub-projects:
- OpenCA PKI, a full featured PKI package.
- LibPKI, a library for PKI application development.
- OpenCA OCSPD, a small, robust Online Certificate Status Protocol daemon.
- PRQPD Server, a PKI Resource Query Protocol daemon for use in conjunction with the PKI package.
- OpenCA-ng, a planned project to implement new features and overcome limitations of the current project. (ng stands for "Next Generation")
