To send an encrypted message to someone, you\u2019ll need to know their public key. Signing your outgoing message with their public key allows them to then decrypt it with their private key. End-to-end encryption makes it nearly impossible for anyone to intercept your message. As the name suggests, you should never reveal your private key to anyone.<\/p>\n<p>Using PGP in most email clients requires the use of additional software (like <a rel=\"nofollow noopener\" target=\"_blank\" href=\"https:\/\/flowcrypt.com\">FlowCrypt<\/a> or <a rel=\"nofollow noopener\" target=\"_blank\" href=\"https:\/\/www.mailvelope.com\">Mailvelope)<\/a>\u00a0to handle the decryption and encryption process. But ProtonMail already supports OpenPGP natively, which means that you can set it up for use with specific email addresses and then forget about it.<\/p>\n<p>You can use PGP with a free ProtonMail account or a paid one\u2014either way.<\/p>\n<blockquote class=\"admonishment_tip\"><p><strong>Tip:<\/strong> If you\u2019re already sending an email to another ProtonMail user, then you don\u2019t need to worry about this, since messages sent between ProtonMail addresses are already end-to-end encrypted anyway.
