Understanding Encryption Error in Outlook

Suppose you’re sending a secret message to your friend through the Internet. Encryption puts that message in a special locked box to which only you have keys. This box keeps your message safe from anyone trying to peek at it while it travels through the internet. When your friend gets the box, they use their key to unlock it and read the message. This way, even if someone tries to snoop on your message while it’s moving around online, they can’t understand it because it’s locked up tight!

For example, when you send emails, they’re like messages in locked boxes. They use something called the public key infrastructure (PKI), which gives everyone a pair of keys: one key to lock the box (public key) and another key to unlock it (private key), both in the form of special digital codes. This way, only you and the person you’re emailing can read what’s inside, keeping your messages safe and private.
