Encryption

The main idea is that we live in a world without privacy, that by only sending and email you are giving ideas of were do you live, what do you like and what do you do. So he and his partners of the CERN made a via of comunication called ProtonEmail, which allows you to send an encrypted email to the person you want, without leting the server to see it.This has been such an excellent idea that if you want to send a proton mail you cant as the server is full. The differences with other emails, is that you can send an email which is encrypted and the server can`t see it, no one can see your mail, except the receiver so the ProtonMail is a private website while hotmail is a public email.

How it works?

When the user creates  a proton mail account, their browser creates a pair of private and public keys, the public key is used to encrypted the users email and  The private key, which is capable of decrypting the user's data, is symmetrically encrypted with the user's mailbox password in the user's web browser and then both keys are then stored on proton mail servers.
