GG-AESY is a tool for its automation sealing. It is written in C #, using multiple classes and functionally object-oriented.
GG-AESY is on GitHub: https://github.com/jfmaes/GG-AESY and does the following:
Can hide AES-256 encryption keys or both keys and IV's (Initialization Vectors)
It can hide payloads both encrypted and unencrypted
Hiding is done in 2 different ways:
Random mode: Hide wherever possible without damaging the JPEG
Append mode: add at the end of JPEG.
In addition to stegano, GG-AESY will also encrypt your file / payload, and any extensions needed for byte encryption to work.
GG-AESY is also capable of decrypting payloads using JPEGs to extract the / IV / payload key.
GG-AESY can NOT decrypt and run in memory. This has its reason: because the GG-AESY itself is not supposed to be a weapon in itself. Do not hesitate to write your own custom loaders in any language you prefer.
The application as you understand it is aimed at experienced users and developers. If you do not make sense of the above take a look here
