Quick Start

Encryption:
1. Set a password.
2. Write or paste a text into the "Unencrypted Text" area (green bordered).

4. The decrypted text will appear in the "Unencrypted Text" area (green bordered).
5. Copy the text and use it wherever you want.

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.
