What’s encryption?

Basically, encryption is a way to transmit a message in code. The only person who can decode the message is the person with the right key; to anyone else, the message looks like a random series of letters, numbers, and characters. Encryption is essential if you are trying to send sensitive information that other people should not be able to access. It’s very important to add this extra layer of security to sensitive information, because email messages are sent over the Internet and may be seized by an attacker.
