Encryption. What’s all the fuss about?

""

Encrypted data looks like gibberish to anyone who intercepts it — it is impossible to read.


Encryption is one of the most important security measures in use today. It is used to securely login to websites, shop online, and protect your devices if they get lost or stolen by encoding the data so it is not readable without a decryption key.

Look for SSL’s lock icon in the address bar.
Make sure you only enter your credentials on known websites that use SSL. Look for the lock icon in your web browser. If you get a warning about an invalid certificate don’t proceed. It may be a sign of an insecure or compromised site.

Your smartphone needs a password.
When you set up a password or PIN for your iOS or Android smartphone, it will automatically encrypt your entire device. Here’s 2 good reasons why you want to set up a PIN:
your device will be locked when not in use,
the data on your device won’t be accessible if it is lost or stolen.

Encryption is built into operating systems.
Windows and macOS have encryption built into their operating systems. All you need to do is enable it. Once your computer is encrypted it won’t be accessible without your password or decryption key. Ensure you have a backup before you proceed.
Macalester computers are encrypted at setup to ensure data is secure for the lifecycle of the device.

Chat securely.
Most chat, messaging and SMS services are not encrypted. Use Signal - Private Messenger to secure your personal communications.
