Encryption is the process of encoding messages or information in such a way that only authorized parties can read or access them. This is done through the use of a mathematical algorithm and a secret key. The message is encrypted using the algorithm, and the key is used to decrypt it. Without both the algorithm and key, it's impossible to read the message.Encryption has been used for centuries to protect sensitive information. It's essential for keeping data secure online, especially when sending credit card numbers or other personal information. Encryption also helps keep communications private, which is important for businesses and governments alike.Despite its many benefits, encryption can also be used for nefarious purposes. Hackers often use encryption to disguise their activities from authorities and security professionals. Terrorists have also been known to use encryption as a way to hide their communications from intelligence agencies.
