PISS (Picture Secret Steganography) is a command line tool to encode/decode secrets into/from image files using LSB steganography.
piss --help for usage.
cargo install piss
Encode a secret into an image
piss encode samples/the-matrix.jpg samples/secret.txt samples/the-matrix-reloaded.png
Image with secret:
Recover secret from image:
piss decode samples/the-matrix-reloaded.png samples/secret-reloaded.txt
By default, PISS uses 2 bits per image byte to encode the secret, you can change this value if desired:
piss -b 4 encode samples/the-matrix.jpg samples/secret.txt samples/the-matrix-reloaded.png
Just remember to decode using the same number of bits, otherwise the output will be garbage:
piss -b 4 decode samples/the-matrix-reloaded.png samples/secret-reloaded.txt
It is not recommended to encode secrets and save the output as
.jpg as compression is performed and the secret is lost.
Supports from 1 to 8 bits secret encoding
The user can specify the number of bits of the secret to use per image byte
Change between image formats
It is possible to convert the image format during encoding, just set a different extension for the output.
