End-to-end encryption is the most secure way to communicate privately and securely online. By encrypting messages at both ends of a conversation, end-to-end encryption prevents anyone in the middle from reading private communications.

Until recently, end-to-end encoding ( E2EE ) was the sole knowledge domain of the technical school grok because of the complicate operations required to use it. however, recent technological advances have made end-to-end encoding much easier to use and more accessible. In this article, we will explain what is end-to-end encryption and what advantages it offers over regular encryption.

What is end-to-end encryption (E2EE)?

When you use E2EE to send an electronic mail or a message to person, no one monitoring the net can see the content of your message — not hackers, not the government, and not even the caller ( for example, ProtonMail ) that facilitates your communication .
This differs from the encoding that most companies already use, which only protects the data in transportation system between your device and the company ’ s servers. For example, when you send and receive an e-mail using a service that does not provide E2EE, such as Gmail or Hotmail, the ship’s company can entree the content of your messages because they besides hold the encoding keys. E2EE eliminates this possibility because the service provider does not actually possess the decryption key.  Because of this, E2EE is much stronger than standard encoding .

How does end-to-end encryption work?

To understand how E2EE works, it helps to look at a diagram. In the example below, Bob wants to say hello to Alice in private. Alice has a public keystone and a individual winder, which are two mathematically refer encoding keys. The public key can be shared with anyone, but entirely Alice has the private key.

first, Bob uses Alice ’ s public key to encrypt the message, turning “ Hello Alice ” into something called ciphertext — scrambled, apparently random characters .

Bob sends this code message over the public internet. Along the means, it may pass through multiple servers, including those belonging to the e-mail avail they ’ re using and to their internet service providers. Although those companies may try to read the message ( or even share them with third gear parties ), it is impossible for them to convert the ciphertext second into clear plaintext. only Alice can do that with her private winder when it lands in her inbox, as Alice is the only person that has access to her secret key. When Alice wants to reply, she just repeats the process, encrypting her message to Bob using Bob ’ s populace key .

Advantages of end-to-end encryption services

There are respective advantages of E2EE over the standard encoding that most services utilize :

  • It keeps your data safe from hacks. E2EE means fewer parties have access to your unencrypted data. Even if hackers compromise the servers where your data is stored (e.g., the Yahoo mail hack), they cannot decrypt your data because they do not possess the decryption keys.
  • It keeps your data private. If you use Gmail, Google can know every intimate detail you put in your emails, and it can save your emails even if you delete them. E2EE gives you control over who reads your messages.
  • It’s good for democracy. Everyone has the right to privacy. E2EE protects free speech and shields persecuted activists, dissidents, and journalists from intimidation.

These are the reasons we built ProtonMail. As the beginning and largest procure electronic mail provider, we protect millions of users every day. throughout encoding is the technological anchor of our vision for a more secret and batten internet .
