Projects
I'm working on eduVPN. The eduVPN project provides a fully managed VPN solution, for education and research capable of handling many different VPN scenarios and able to replace most (commercial) VPN solutions to provide a fast, flexible, secure and not to mention, fully free software VPN service for any organization, scaling from a Raspberry Pi to multi server 10 Gbit setups.
Another project I am working on is php-saml-sp which offers a minimalistic, but fairly complete implementation of a SAML SP.
