It's an example of cryptography. Information is concealed or coded using cryptography so that only the recipient of a communication can decipher it.
Since ancient times, messages have been coded using the technique of cryptography, which is still utilised today in e-commerce, bank cards, and computer passwords.
Algorithms and cyphers used in contemporary cryptography, like 128-bit and 256-bit encryption keys, allow for the encryption and decryption of data. Modern cyphers are thought to be nearly impenetrable, such as the Advanced Encryption Standard (AES).
The practise of encoding data to ensure that only the person a message was written for may read and process the information is a typical definition of cryptography. The field of cybersecurity known as cryptology combines elements of computer science, engineering, and mathematics to produce sophisticated codes that conceal a message's real meaning.
