![]() ![]() The private key is kept secret and is used for decryption. The public key can be distributed to anyone who wants to send you a message and is used to encrypt a message that can only be decrypted by you. PGP works by generating a key pair: a public key and a private key. Using PGP with Proton Mailīy far the easiest way to use PGP with someone else is for both you and your contact to create a Proton Mail email address (new window). To provide end-to-end encryption between Proton Mail and external email providers, Proton Mail provides two options: Password-protected Emails (new window) and PGP encryption. While we store your emails in an encrypted format on our servers, the external email provider of the person you are emailing might have access to the emails you send. Proton Mail can also be used to communicate with external email accounts without end-to-end encryption. Additionally, all messages in Proton Mail inboxes are protected with PGP encryption to prevent us (or anyone else) from reading or sharing your emails, a concept known as zero-access encryption (new window). ![]() With Proton Mail, anyone can use PGP regardless of their technical knowledge.Īll messages between Proton Mail users are automatically end-to-end encrypted. We have built Proton Mail with PGP fully integrated, so you don’t need to take any additional steps to use PGP encryption. Historically, PGP was difficult to use, and impossible for most users to set up and regularly use for their own email communications. PGP is a proven method of protecting email communication with end-to-end encryption (new window) (which prevents emails from being read by any third parties, including your email provider). ![]()
