End to end encrypted email service - ProtonMail

In this post we will learn about End to end encryption and also how to use ProtonMail to Send Private and End to End encrypted emails.

What is End-to-End Encryption

End-to-End Encryption (E2EE) is a method of encryption in which only the Sender and Receiver can read the Messages or data.

Contrary to that in Traditional Encryption, in E2EE the Government, your ISP or Even the Company itself cannot read your Messages and Data.

In E2EE, the Encryption and the Decryption keys are independently generated on Sender and Receiver side respectively based on a common public key. The actual key is not transmitted in between them

So it is not possible for Hackers and even the Company through which you are sending messages to read your Data/Messages.
