In this post, we will show you why end-to-end encryption is ideal instead of TLS.
Email communication is a pretty fascinating thing that we all have become used to using on an hourly basis. You can attach files, send to multiple people at once, and design every email with signatures and images.
But nobody necessarily understands or thinks about what is happening behind the scenes when sending an email. We just type in our message, recipient, and send the email. In the background of every email you send and receive, things like protocols, certificates, and servers are involved in the process of sending your email messages.
Most email providers are not using the most secure safety measures and it should be something every should be thinking about, especially if you send important files via email.
Here’s why it’s important to encrypt your emails and how to make sure you’re doing what you should in order to keep your emails safe and secure.
TLS vs. End-to-End Encryption
First, let’s look at what TLS and End-to-End Encryption are:
What is TLS?
In short, TLS (Transport Layer Security) is a security protocol made to keep communication private and secure over the Internet. It works with regular email communication, as well as messaging and VOIP.
TLS can help protect you from data breaches and more, which has become very important in today’s world where important information is sent online and you are susceptible to hacking attacks.
There is a three-step process for every TLS connection:
- Keeps data hidden from third parties not involved in the communication.
- Makes sure that both parties are who they say they are.
- Ensures that the information is original and has not been changed.
One of the main vulnerabilities to using a TLS connection is the many touchpoints involved and having a ‘man-in-the-middle’ attack through the encryption process.
What is End-to-End Encryption?
End-to-End Encryption is how we keep our private online messages, photos, information, and files out of the wrong hands. To date, it is one of the safest ways to keep your online communication private and can be especially important to those people who send important information.
E2EE makes sure the entire line of communication is encrypted so nobody can intersect any message or file in the process of sending and receiving.
E2EE can be quite confusing but, in short, goes like this:
- The sender uses the Receivers Public Key to encrypt a message.
- The Sever sees no plain text, only the encrypted message.
- The message can only be opened when the Receiver uses their Private Key (which only they have) to open the message.
- The receiver reads the message.
Obviously, things are much more complicated when using End-to-End Encryption, but this should give you an idea of how it works on the surface.
Why Use E2EE?
E2EE is built into your hardware and software, meaning it’s something that just happens and doesn’t involve a ton of work. E2EE keeps your data safe from hacks and keeps everything private.
In a world where important information is shared online through email and other messaging apps (like Whatsapp and private messaging), E2EE can keep you safe from things like identity theft and the exposure of files you want to keep safe.
How to Get Your Emails End-to-End Encrypted
Well, the process of End-to-End Encryption is complex and deep, which means you can’t do it yourself. That’s why an email encryption add-in is the way to go right now.
Add-ins like Permido allow you to secure your emails with E2EE and, on top of that, become GDPR-friendly. Permido allows you to safely use your email with the click of a button so you don’t have to worry about having someone hack your data or reading your messages.
With all the complexities around encryption, who would have guessed that you can keep yourself safe through the use of a simple plug-in!
