![]() Until enough clients are reliably patched, sending PGP-encrypted messages can create adverse ecosystem incentives for others to decrypt them. Sending PGP messages to others also increases the risk that they will turn to a vulnerable client to decrypt these messages. Since PGP is used as a communication tool, sending messages to others with unpatched clients puts your messages at risk, too.

It can be hard to imagine a workflow without PGP once you’ve taken the time to learn it and incorporate it in your communications. If you’re like us, you likely have recommended PGP as an end-to-end encrypted email solution in workshops, trainings, guides, cryptoparties, and keysigning parties. For users who have few-or even no-alternatives for end-to-end encryption, news of these vulnerabilities may leave many questions unanswered.ĭigital security trainers, whistleblowers, journalists, activists, cryptographers, industry, and nonprofit organizations have relied on PGP for 27 years as a way to protect email communications from eavesdroppers and ensure the authenticity of messages. Researchers have developed code exploiting several vulnerabilities in PGP (including GPG) for email, and theorized many more which others could build upon.
