Steganography
- • A steganographic feature is included (concealing a text within an image - JPG). A steganographic algorithm (F5 algorithm) is used in combination with chosen symmetric cipher algorithm to make a final steganogram (JPEG image).
- • IMPORTANT NOTE: Some applications for communication (like WhatsApp, Viber, Messenger, ...) can resize or recompress images to lower bandwidth. Concealed data are corrupted during the process (JPGs use lossy compression) ⇒ please try all your intended workflows and usecases to verify the process.
Make Steganogram:
1. Set a password.
2. Write or paste a text you want to encrypt (and conceal) into the "Unencrypted Text" area (green bordered).
3. Press the "More" button (middle-right - button with three dots).
4. Choose "Encrypt and Make Steganogram".
5. Select a carrier image (jpg, png, bmp).
6. Press the "Continue" button.
7. The steganogram will be made and saved.
Decrypt from Steganogram:
1. Set a password.
2. Press the "More" button (middle-right - button with three dots).
3. Choose "Decrypt from Steganogram".
4. Select a steganogram.
5. The decrypted text will appear in the "Unencrypted Text" area (green bordered).
6. Copy the text and use it wherever you want.
