Pretty Good Envelope (PGE)
From Just Solve the File Format Problem
Pretty Good Envelope (PGE) is a DOS program that hides files by appending them to other files and optionally encrypting them.
It hides a message file in another file by the very simple method of appending the message to the file, and then appending a 4 byte little endian number which points to the start of the message.
It says it's for GIF or JPG images, but it will work with any file.
- v1.0 - by XCrypt Productions (Roche'Crypt)
- v2.0 - by Robert G. Durnal removes the encryption but adds PGECLEAR, which removes the hidden data from a file
