outguess

OutGuess is a universal tool for steganography that allows the insertion of hidden information into the redundant bits of data sources. The nature of the data source is irrelevant to the core of OutGuess.

The program relies on data specific handlers that will extract redundant bits and write them back after modification. The supported formats are JPEG, PPM and PNM.

This package is useful in forensics investigations and security actions.
