The Ultimate Guide to Email Encryption
Learn the differences between transport-level and end-to-end encryption.

Pretty Good Privacy (PGP)

PGP is the gold standard for End-to-End Encryption (E2EE). It uses asymmetric cryptography: you have a Public Key (to lock) and a Private Key (to unlock).

How it works:

  • Alice wants to send a secure email to Bob.
  • Alice asks Bob for his Public Key.
  • Alice writes the email and encrypts it using Bob's Public Key. It now looks like gibberish.
  • Alice sends the email over the internet. Even if a hacker or the email provider (like Gmail) intercepts it, they cannot read it.
  • Bob receives the email and decrypts it using his Private Key.
Pros: Maximum security, provider-agnostic.
Cons: Hard to set up, requires both parties to manage keys manually.
