To write encrypted messages, where instead of letters there would be mysterious symbols and incomprehensible signs, you can simply change the font in the computer. But only true lovers of ciphers and languages are able to create their own, unique system of symbols and signs.
Instructions
Step 1
The simplest option is to write a personal alphabet, replace the Cyrillic alphabet with your own characters, or borrow them from other languages. For example, Korean, Japanese or Sanskrit. An intricate hieroglyph will be the usual letter A, and the diacritical mark next to it (check mark, dash, circle) will denote a number or the simplest arithmetic relations: addition, subtraction, multiplication and division.
Step 2
Lovers of encryption, riddles and simply enthusiastic lovers of linguistics are quite capable of creating their own language, where each sign would denote not a sound (or a group of sounds), but a syllable or a larger semantic unit. Examples can be found in ancient languages: Sanskrit, Ancient Egyptian. Their features can be combined with the grammatical base of some modern artificial languages. The most famous is Esperanto, which is over 120 years old and is spoken by several million people. Its alphabet is based on Latin. Loglan (www.loglan.org). Its creator, James Cook Brown, decided to create a language free from logical inconsistencies. The Lord of the Rings creator John Tolkien dedicated his life to the creation of the Quenya language, its alphabet is called Tengwar (https://tengwar.by.ru). These are very beautiful characters, however, Latin is most often used for writing in this language
Step 3
There are enough paid and free resources on the Internet that allow you to encrypt fairly large amounts of texts. The result is a set of characters absolutely incomprehensible to anyone except the decoder program. For example, a set of Latin alphabet characters, numbers, and special characters TlcxeVpqVTJkelZpY1YxamFHZG1aR2huWmtwR1JVZDJaMk5tVzExalpHbGxiazFIUkhOMFpHNWlkbHRkWTJabmRHUmxTa2RHU21odVpXaG5XMTFqWm1wb1oyWm1iRnRkWTJaa2FtaG5aR3BvWjJSdloyWmtXMTFqYm1obmVWTjVaMlpiY1dJMWR6WTFabkp0TlE9PQ ==
