skocur/image-cipher

Steganography software for encrypting text into image that uses modified version of LSB (Least Significant Bit) algorithm.

image-cipher's Issues

Add permission asking (Android)

Add - asking user for permission to access smartphone's storage in order to fetch image and process it. According to this, for now, app works only on Android devices that have OS system version lower than 6.0.

This feature can be implemented in MainActivity as it is "starter" activity for the Image Cipher.

Add Button that will save image

User can process image with few options available to choose from GUI created in FXML file.

Add Button (in specified FXML file) that will be responsible for saving processed image to file. After it, implement feature that will enable user to do so. Here is "TODO" comment that will help: code.

It would be nice to attach (in comment under this issue) screenshot that shows modified GUI.

RSA Encryption

Implement valid RSA Encryption in RSAEncryption.java that will work with all RSA public key formats.

It would be good if this code could use LowLevelBitEncryption. Something like presented below:

Encrypter encrypter = new LowLevelBitEncryption(fileName);
encrypter.encrypt(new String(encrypted, StandardCharsets.UTF_8));

where encrypted is variable that holds encrypted (via RSA) data.
