Chat Analyzer

Python
Java
Private repository.
Developed a Windows desktop app that decrypts locally stored databases of a popular messaging service and monitors user chats for potentially sensitive topics.

There exists a version of the messaging service that stores the user messages locally, in an encrypted SQLite3 database. By finding a key stored in memory and decrypting this database, it is possible to analyze the activity of a user and monitor the chat messages.

Made with Java and its JavaFX GUI framework.
