Do you need to send a secret message? Do you want to text a friend about a d*ckhead at work with the guarantee of no future comebacks? Yes? Great! You're at the right place!

Why Encrypt Messages?

Texting is now so common among the iGenerations, it is not unusual for parents to message their kids to come downstairs for dinner or for a young couple to text each other while in the same shop. It's getting ridiculous. What next? "Yes, like that." "Slower." "Harder."

The main problem with texting every aspect of your life is the permanent record it creates, which can be accessed years later. Your message might have been private when you sent it, but bear in mind that it will always be there for future scrutiny. Even deleted messages can be recovered. So, if you're planning on calling the new guy at work an idiot, ring your friends and tell them, or wait until you can tell them face to face. Don't text them or email them. That will create a permanent record with the potential to haunt you. For example, Mr. Idiot might request a copy of every work message that mentions him, which he is legally entitled to do. It happens a lot. Ask your HR or IT department. So, if you're using a work phone, a work PC, or a work email, you must be über-careful about what you say.

Don't worry though. We've got you covered. The encryption tool on this page allows you to encrypt your messages in a second. It's free, and it will always be free.

Look at this message:

Do you know what it says? No, of course you don't. Could you work it out? Not a chance. Well, if you've got a state-level supercomputer and you know the encryption method, then you might, might, have a chance. Basically, it's about as secure as messaging gets. (Here's a challenge: If anyone can tell me what that message says, I'll send them a nice bottle of Champagne.)

So, are you ready to protect yourself? Are you ready to get sneaky? Use this tool to send highly encrypted messages on WhatsApp, by email, or whatever. Be safe. Enjoy.

Enter Your Secret "Crypto" Word

This word is required to encrypt and decrypt the message. You and the message receiver must know it. It can be any word, phrase, or string of characters.

Encrypt Your Message

Decrypt Your Message

Enter the secret crypto word above, then enter your encrypted message.

Message Encryption Tool

This tool allows you to encrypt and decrypt messages. Once you have your encrypted text, you can send it to your contact using WhatsApp (or any messaging, social-media, or email app). If someone finds your encrypted message, they will only be able to decrypt it if they know your secret "Crypto" word," and they know about this page. Below is an explanation of how the encryption works. Do not worry though. Knowing how it works is no help to someone who wants to decrypt it, unless they have a state-level supercomputer and a lot of time to spare.

This tool currently does not support emojis. If you want us to add that feature, let us know using the "Help Us Improve" contact form below.

How Does This Encryption Work?

This 5-minute video shows how the encryption is performed. As you will see, your message is extremely safe!

Summary of the Encryption Method

This encryption method:

(1) Converts each character to a decimal number (its ASCII code).
(2) Converts each number to a hexadecimal number.
(3) Converts each number (not letter) in the hexadecimal to a letter.
(4) Places the text horizontally in a table whose size is determined by your secret word.
(5) Regathers the text vertically from the table in an order determined by your secret word.
(6) Inserts random padding letters to further obfuscate.

Every run of the encryption and decryption offers a specific explanation, but, if you watch the video, you'll understand why your message is still extremely secure.

How Secure Is This Message?

We provide an explanation of how every message is encoded. This, however, does not mean that the message is insecure. It is, in fact, extremely secure.

If a person who wanted to decode this message did not understand the mechanics of the encoding, they would have zero chance of decoding your message. If, however, the decoder did understand the encoding-decoding system, then they would still have extreme difficulty with decoding a message. Before they could start decoding, they would need to know the secret word's length and the order of its columns (or the secret word itself). There are no clues in the encrypted message to the secret word's length or the order of its columns.

Also, the decrypted message is not stored anywhere by us. So, there is no history to check and no deleted files to recover. Once you've left this page, the message is gone forever. As a worst-case scenario, it will exist in its encrypted form in whatever application you used to send it.
