Static Methods

decode({required File image, String? unencryptedPrefix, EncryptionType encryptionType = EncryptionType.symmetric, String? encryptionKey}) → Future<String?>

Extracts embedded text from image. If encryptionKey is provided, resulting embedded text (if any) will be assumed as encrypted from encode hence decode will try to decrypt it with encryptionKey symmetrically or asymmetrically depending on specified encryptionType.

decodeBytes({required Uint8List bytes, String? unencryptedPrefix, EncryptionType encryptionType = EncryptionType.symmetric, String? encryptionKey}) → Future<String?>

Extracts embedded text from image. If encryptionKey is provided, resulting embedded text (if any) will be assumed as encrypted from encode hence decode will try to decrypt it with encryptionKey symmetrically or asymmetrically depending on specified encryptionType.

decodeFile({required File image, String? unencryptedPrefix, EncryptionType encryptionType = EncryptionType.symmetric, String? encryptionKey}) → Future<File?>

Extracts embedded file from image. If encryptionKey is provided, resulting embedded file (if any) will be assumed as encrypted from encodeFile hence decodeFile will try to decrypt it with encryptionKey symmetrically or asymmetrically depending on specified encryptionType.

encode({required File image, required String message, String? unencryptedPrefix, EncryptionType encryptionType = EncryptionType.symmetric, String? outputFilePath, String? encryptionKey}) → Future<File?>

Writes message into image without altering rgb channels and returns image file with message embedded.

encodeBytes({required Uint8List bytes, required String message, String? unencryptedPrefix, EncryptionType encryptionType = EncryptionType.symmetric, String? encryptionKey}) → Future<Uint8List?>

Writes message into bytes without altering rgb channels and returns image bytes with message embedded.

encodeFile({required File image, required File fileToEmbed, String? unencryptedPrefix, EncryptionType encryptionType = EncryptionType.symmetric, String? outputFilePath, String? encryptionKey}) → Future<File?>

Embeds fileToEmbed in image and returns resulting image file.

generateKeypair() → SteganographKeypair

Generates a keypair with public and private keys for asymmetric encryption.
