PGE - Pretty Good Envelope

Hides data file into a GIF or JPG file of any size or resolution using a 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. The encryption used is considered "weak" by the author, using another encryption method prior to applying PGE is recommended.

Stego

Stego by Romana Machado is a steganography tool that enables you to embed data in Macintosh PICT format files, without changing the appearance or size of the PICT file. Thus, Stego can be used as an "envelope" to hide a previously encrypted data file in a PICT file, making it much less likely to be detected.
