OpenXPKI is a Web and CLI-based enterprise-grade PKI/trust center system (X509 public key infrastructure) complete with CA, Web interfaces, offline support, and support for well established infrastructure components like RDBMS and Hardware Security Modules. Flexibility and modularity are the project's key design objectives. Unlike many other PKI solutions, it offers powerful features necessary for professional environments. However, small scale installations are also targeted by providing quick-start configuration examples that allow you to get a usable PKI running quickly.
Mojolicious is "Duct Tape For The HTML5 Web". It is powerful with no dependencies out of the box with RESTful routes, plugins, Perl-ish templates, session management, signed cookies, asynchronous client, a testing framework, a static file server, first class Unicode support, and much more. It has a clean, portable, object oriented pure Perl API without any hidden magic and no requirements besides modern Perl, but can use many CPAN packages out of the box. It has a HTTP 1.1 and WebSocket client/server implementation with TLS, IDNA, Comet (long polling), chunking, and multipart support, and an async I/O Web server supporting EV pluggable event queue, Unix domain sockets, and hot deployment. Automatic CGI, FastCGI, and PSGI detection allows for any deployment situation. It has a JSON and XML/HTML5 parser/emitter with an advanced CSS3 selector support and DOM.
