Pretty Good Privacy (PGP) is a program to encrypt your emails, texts, files, etc. As emails on Gmail, Yahoo, Outlook and other popular email services are stored in cleartext, PGP can be a solution to keep your emails from being read & analyzed by these big techs.
PGP is based on public-key cryptography. Essentially you have 2 keys: a public key and a private key. Your public key is known to everyone whereas only you have access to the private key. Message encrypted with the public key can only be decrypted with the private key. You can learn more about PGP on openpgp.
In practice, if someone wants to send you a secret message that only you can read, this person encrypts the message using your public key.
Without PGP the emails sent to an alias are forwarded by SimpleLogin as-is to your mailbox, leaving anyone in-between or your email service able to read your emails.
With PGP enabled, all emails arrived at SimpleLogin are encrypted with your public key before being forwarded to your mailbox.
As emails are not stored on SimpleLogin, only you can read your emails.
If you upload your PGP public key on SimpleLogin, only you can now read the emails sent to your aliases.
You can create and manage your keys when adding/editing your mailboxes. Check it out your mailbox dashboard ↗.
As PGP encryption is resource intensive, this feature is only available in the Premium plan or during the trial period.
After the trial, SimpleLogin stop encrypting the forwarded emails.
