stegify-flutter-plugin #

Flutter plugin for fully transparent hiding any file within an image using stegify API. This technique is known as LSB (Least Significant Bit) steganography

Demonstration #

CarrierDataResult
Original FileEncoded FileEncoded File

The Result file contains the Data file hidden in it. And as you can see it is fully transparent.

Usage #

flutter-stegify plugin offers an easy to use Dart functions for steganography encodin/decoding. The original implementation is in Go and can be found here: stegify

This plugin uses go-mobile for generating platform native bindings and exposes Dart functions which can be used directly in your flutter mobile application!

API #

void encode(String carrierFileName, String dataFileName, String resultFileName) async
void decode(String carrierFileName, String resultFileName) async

encode performs steganography encoding of data file in carrier file and saves the steganography encoded product in new file.

decode performs steganography decoding of data previously encoded by the Encode function. The data is decoded from file carrier and it is saved in separate new file

NOTE: The result file won't have any file extension and therefore it should be specified explicitly in the resultFileName argument.

Disclaimer #

If carrier file is in jpeg or jpg format, after encoding the result file image will be png encoded (therefore it may be bigger in size) despite of file extension inherited from the original carrier file (which is .jpeg or .jpg).

0.0.1 #

flutter-stegify plugin offers an easy to use Dart functions for steganography encodin/decoding. The original implementation is in Go and can be found here: stegify

void encode(String carrierFileName, String dataFileName, String resultFileName) async
void decode(String carrierFileName, String resultFileName) async

encode performs steganography encoding of data file in carrier file and saves the steganography encoded product in new file.

decode performs steganography decoding of data previously encoded by the Encode function. The data is decoded from file carrier and it is saved in separate new file

NOTE: When encoding the file extension of result file is inherited from the carrier file and must not be specified explicitly in the resultFileName argument.

NOTE: When decoding the result file won't have any file extension and therefore it should be specified explicitly in the resultFileName argument.
