What is encryption?



The science of encoding and decoding secret messages, also known as encryption, has been around for hundreds of years. The ancient Greeks used to use cryptography to protect secret information from enemies. In modern times, encryption is applied to online security.

Encryption allows tech industries to convert sensitive data into a secret code to protect it from unauthorized people, especially cybercriminals and hackers. Being aware of when encryption is used can help you understand whether your information is properly protected, or whether you’re at risk of a privacy breach!
