Seagul
This command line utility encodes and decodes arbitrary information in images.
Installing
The easiest way to install is through cargo
cargo install seagul
Encoding
Passing data inline
seagul encode -d "Super secret message" path/to/source/image path/to/output/image
Getting data through STDIN
cat my_secret_file | seagul encode path/to/source/image path/to/output/image
Outputting to STDOUT (omit the target image)
seagul encode -d "Super secret message" path/to/source/image
The default channel used for encoding is the blue channel. To change it, use the --channel
option.
seagul encode -d "Super secret message" --channel green path/to/source/image
For more encode options, see the integrated help with seagul encode --help
Decoding
The decoder supports the same options as the encoder, with the addition of a --marker
option to stop decoding when the specified byte sequence is found.
seagul decode path/to/image
# Stop at "end of sentence." sequence.
seagul decode --marker "end of sentence." path/to/image
