PGP encryption is a type of cryptographic authentication system that can help keep your emails away from prying eyes. The downside? It’s a bit tricky to set up and requires some technical savviness — especially on iOS. Luckily, Canary Mail is an app that does the hard work for you. It isn’t free, but it works.
Canary is an email client available on iOS and macOS that features baked-in PGP encryption. It also works with your existing email accounts, so you can encrypt your Gmail or iCloud messages. PGP is available in both auto mode, which requires that the recipient also uses Canary, or manual for those who are already familiar with PGP encryption.
