JSalt since March 20th, 2011
JSalt (JSalt: https://github.com/pplupo/jsalt) is an open-source library which provides an easy, fast and safe way to encrypt passwords using salted hash algorithms compatible with JCE. The encrypted password may be generated in hexadecimal or encoded in base64. Besides that JSalt provides a password comparator that is safe against time attacks. The comparison time varies per length of the tested string and not the password's no matter the password's length, making it impossible for an attacker to find out even the length of the password in time comparison attacks. Currently hosted at GitHub: https://github.com/pplupo/jsalt.

Trilobyte since April 24th, 2014
Trilobyte is an Android App available at Google Play which allows an employee to check his worked hours recorded in REP 1000 models from Trilobit (electronic devices that record when the employee arrives and leaves the workplace). This app was developed by reverse-engineering the UDP network packets captured during the communication of the official desktop software and the device. To do that it was necessary to break down the data fields of the UDP packages, determine how the checksum was calculated, how the packages receiving was controlled and other details (https://play.google.com/store/apps/details?id=com.pplupo.trilobyteapp).
