SMS Encryption can be used to encrypt or code any text message with a pass code, so only the person with the pass code can decrypt the message sent to you. Then send the message via SMS or Email.
Simply enter your text in the text box, then enter your unique pass code using numbers and/or letters then press encrypt, and presto, you have your encrypted message.
You don’t need to remember the pass codes, tell your friends the pass code then you can save them for future use.

Send messages to your friend with a hint of the passcode, get them to try and guess to get your pass code.
However, it is only recommended for fun and private use, and not to be used for any illegal activity.
