Ciphers, anagrams, rebuses are not only an exciting workout for the mind, but also a very useful skill in extreme cases. Anyone can learn the art of encryption. And having acquired a certain practice, you will be able to compose your own methods.
It is necessary
- - paper and writing materials;
- - computer keyboard.
Instructions
Step 1
If you decide to learn how to encrypt text, then you probably have a need to hide certain information from others. This is especially true now. After all, no channel for transmitting information is absolutely reliable. Constant hacker attacks on mail servers and databases of cellular operators make us think about our own information security.
Step 2
When practicing encrypting text, start with the basics. The easiest way is to use first letter encryption. You write the most ordinary text, but the first letter of each line vertically will make up an encrypted message (Fig. 1).
Step 3
This encryption method will help you if ill-wishers force you to write a note to your family and convince them that you are okay. Outwardly, the text will perfectly meet all their requirements, but you can send a "distress call" (provided that your family also know this encryption method).
Step 4
Another simple encryption method is based on the use of a computer keyboard. Each key for typing contains two letters - Russian and Latin. To encrypt the phrase "I'll come tomorrow", type this text, switching to the English layout. Then you get “Z ghbtle pfdnhf” (Fig.2). To decipher your message, the interlocutor must perform the opposite action - type the English text in the Russian layout, or use the services of specialized sites (for example, https://klava.biz/index.php, https://androidpage.ru/text-converter-konverter-raskladok-klaviatury-v-te…, etc.)
Step 5
It is because of the existence of such services that it is not worth transmitting information of increased importance, encrypted in this way, by e-mail. If your mailbox is hacked, then third parties can decode your message.
Step 6
To truly effectively protect your messages, develop your own encryption system, the key to which will only be known to you and the person to whom you are addressing your messages.
Step 7
You can also take a computer keyboard as a basis. Now come up with a coding principle. For example, conventionally designate keys for typing with numbers (Fig. 3). Some letters will be designated by one-digit numbers, others - by two-digit ones. To avoid confusion, put "/" between numbers. Now encrypt the phrase "He is not guilty." You should get “20/16 16/13 8/15/16/20/8/13/16”.
