What is it?

Encryption is a digital process (such as ciphertext) that converts data into a secret code in order to secure it from unauthorised users.

How does it work?

Encrypting uses computer algorithms (maths formulas) to rearrange the data bits into a form that cannot be used (read) without permission. In order to undo encryption, the matching data key is needed to rearrange the mixed data back into its original form. Undoing encryption is called decryption.

Why is it useful?

Encryption is useful to provide security for data.

What do you need to keep in mind about your children and encryption?

Should sensitive material need to be transferred between computers, it is a good idea for your child to know that encryption is the most secure way to do this.
