What is encryption?
The word encryption comes from the Greek word kryptos, meaning “hidden” or “secret”.
Encryption is a way to maximize the security of i.e. an email message, chat message, call or file by “scrambling” the contents. Encryption is basically a process/method of encoding messages or information in such a way that only authorized parties can read it. Encryption is a safe way to communicate private and securely, without others being able to follow or spy on you.
Imagine you are passing a secret note from the back row of a cinema to your friend who sits in the front row. You pass it on and hope no one between you and your friend decides to open your secret note and read the message. This is similar to how non-encrypted information travels on the Internet. Now imagine placing your note in a heavily secured locked case, that only you and your friend have keys for, and passing this case to your friend. No one can open the case and read your secret note – except you and your friend. Encryption is the online equivalent of a locked case – and only your computer has the keys.
