Encrypted messages are pieces of information that have been transformed into a code to prevent unauthorized access. This process uses algorithms to scramble the original text, making it unreadable to anyone who does not have the correct key or password to decode it. Encryption is commonly used in digital communication to protect sensitive data, such as emails and online transactions. The main purpose of encryption is to ensure privacy and security. For example, when you send a message through a messaging app, it may be encrypted so that only the intended recipient can read it. This helps protect personal information from hackers and other malicious actors who might try to intercept the data during transmission.
