Divmod Vertex is an implementation of Q2Q, a protocol for opening authenticated connections, even through NAT. It allows a user to reliably demonstrate their identity (for distributed authentication) and receive real-time data directly from other users, and provides a mechanism for a user to decide whether they want to expose their IP address to a third party before accepting a peer-to-peer connection. It is byte-stream oriented and application-agnostic. Any peer-to-peer application can use Q2Q to open connections and deliver messages.
The Information Currency Web Services distribution provides an interface to create tradable economic instruments from submitted information. Information currency enables the cooperative mechanisms of "economic calculation" to be directly applied to the management of that information.
Lock Box Labs PGP Tools comprise two command line tools and associated ant tasks for manipulating Open PGP key rings and performing encryption, signing, key generation, and certification operations.

Novosec Bouncy Castle Extensions provides some extensions to the Bouncy Castle Cryptography framework. It features an OCSP (RFC 2560) server and client that work with the Bouncy Castle OCSP generators and parsers, and a full tested implementation of CMP (RFC 2510, RFC 2511) generator and parser classes, that also rely on Bouncy Castle classes.
