Anyway, today I'm going to show you how to use Cryptic SMS app:

2. Open the app, you will see a screen as shown below.

3. Then tap on "ADD CIPHER". A small window will appear:

4. Enter a name for the new cipher and then select a cipher. Then tap on "OK". If a configuration screen appears, configure the cipher as you want and then tap on "OK" (See the typical configuration screen below).

5. After entering the key, tap on the cipher that you just created. You will see an empty window with four options, it is a message box actually (see the image below).

6. Type in the message that you want to sent. Then tap on the "Encrypt" button.

7. After encrypting the text, tap on "Send". then a lot of options will pop up (it depends on your installed apps). Select "Messaging" and then enter the number of recipient. Then send the message.

On Recipient's Device: (Recipient receives the message.)

1. Copy the received message and then open Cryptic SMS app.

2. Add the same cipher in the same configuration as in the sender's device. Then tap on it, paste the SMS on the message box.
