ZedLog is a robust cross-platform input logging tool (A.K.A., a key logger). It is based on a flexible data logging system which makes it easy to get the required data. It features logging of all keyboard and mouse events, a replay simulation tool, logging to a file, and hiding in the background.
The Assimilation Monitoring Project is a highly scalable discovery-driven monitoring system. It integrates continuous discovery of servers, services, service dependencies, switch connections, and lots of other things into the monitoring process. The discovery is "stealthy" and will never set off any network security alarms. Adding servers doesn't measurably increase monitoring load, and the system is expected to easily scale into the 100K server range. The discovery work is distributed among all the nanoprobes (agents), which run scripts that spit out JSON. The central system (CMA) stores these strings and runs optional plugins to create graph nodes.
h2H Messenger is a secure messenger client that uses PHP OpenSSL functions, mcrypt, and PHPSecLib to encrypt messages at-rest using RSA keys. The user only creates an account and the application handles the public key generation, key management, key exchange, and encryption and decryption of messages. There are no algorithms or key sizes to choose. It uses strong standards (AES 256, 4096 bit RSA Keys, SHA1, SHA512, etc.) in the background, and requires two-factor authentication using a code sent via SMS or using Asterisk.
