Application for AES encryption sentences or paragraphs, so that they are protected from eavesdroppers on the use of WhatsApp and mail.

We have used the AES encryption algorithm with 128-bit, 16-character key in the paid version .

And we have used in the Free Version , the DES encryption algorithm, which uses a 64-bit key, key 8 characters.

The application shows two tabs: one of encryption and de-encryption another.

FLAP Encryption:
encryption of "cleartext" with the key is performed and the "ciphertext" is obtained in the paper holder.

Process:
1. Enter the "plain text" keyboard.
1. O pasting from the paper holder. (Option not recommended trace in the carrier paper)
2. Insert the key (8 or 16 characters depending on version).
3. Press button "PROCEED". And the "ciphertext" is automatically pasted into the paper holder.
4. Go to the sending application (WhatsApp or email) and paste the "ciphertext" from the paper holder.

FLAP DES Encryption:
DES-encryption "ciphertext" with the key is performed and the "plain text" is obtained on the screen. [There button to copy into the holder roles].

Process:
1. Go to your application (WhatsApp or email) where you have sent the "ciphertext" and copies it to the paper holder.
2. Enter this application and in this tab (DES-encrypted).
3. Click the button to the left of "ciphertext". This would rub off the "ciphertext" in the box.
        4. Enter the password (8 or 16 characters depending on version).
5. Press button "PROCEED", the "plain text des-encryption" will show on the screen.
6. If you press the copy button, the "plain text des-coded" into the holder paper copies. (Option not recommended to leave mark on the paper holder).

        In both flaps have the option to view or hide the key, the button "eye"
