Different types of e-mail encryption and their benefits

Millions of e-mails are sent around the world every day. Emails are sent from server to server and are temporarily stored in the process. If they are unencrypted, attackers can read them on every server. E-mails can also be intercepted by criminals on their way from one server to another and their content can be falsified. Neither the sender nor the recipient will notice anything.

E-mails with sensitive information should therefore be encrypted. During encryption, readable information (plain text) is converted into its illegible counterpart (ciphertext). The ciphertext can only be made readable again with the help of a suitable key.

Why is it important to encrypt your e-mails?

When you send a letter to someone you know, you hope that he or she is the only one who reads this letter. But a lot can happen to that letter while it’s in transit and there might be curious people trying to read your letter. That’s why we send important messages in a sealed envelope and not on the back of a postcard. Sending and receiving email works in a similar way. However, when you send or receive messages through an email provider that does not transmit messages over a secure connection, attackers could view your emails. Anyone can read unencrypted e-mails. Not only the email provider who evaluates emails for personalized advertising. Also secret services, police and criminals who are interested in your data can read unencrypted mails, regardless of whether it is of a private or business matter.
