PiggyPack by kristopolous is a very basic open source Ruby script for hiding data in 24-bit images.
Technical details
It uses the 8 LSB from each 24-bit RGB triplet (3 LSB from red + 2 LSB green + 3 LSB from blue)
The header is
- 1 byte number specifying the length of the file name
- The filename itself
- 8 byte lsb number specifying the length of the playload
- The payload itself
