WispPGP is a focused OpenPGP toolkit for iPhone. Encrypt, decrypt, sign, and verify text in seconds, or use the Share Extension to protect content from any app and send it as ASCII‑armored .asc. Manage multiple keys, set an active key, and keep your workflow fast and predictable.
Built for iOS 17+, WispPGP keeps cryptography practical: generate key pairs, label keys clearly, and choose whether to share encrypted output as a file attachment or as plain text. The experience is intentionally clean so you can work quickly without losing control of important details. Powered by GoOpenPGP (MIT) for broad OpenPGP compatibility.

Highlights
• Encrypt and decrypt messages with OpenPGP.
• Sign and verify messages to confirm authenticity.
• Generate and manage multiple key pairs with name, email, and comment.
• Set an active key to speed up repeated actions.
• Share encrypted output as ASCII‑armored text or .asc files.
• Use the Share Extension to protect text from any app.
Security & Privacy
• Biometric access is required for private keys and stored passphrases.
• Private keys are stored in iOS Keychain with device-only access.
• No plaintext key files are written to disk.
• Sensitive passphrases are cleared when the app goes to background.
• Optional clipboard auto-clear after pasting.
• The source code is open source, so anyone can review what happens with their private keys.
Security Test Checklist
• Key Manager access prompts Face ID; cancel keeps the screen locked.
• Private key actions (Decrypt/Sign/Export) always prompt biometrics.
• Lockout behavior: repeated failures show the biometry lock message.
• No biometric enrolled: shows a clear not enrolled/not available message.
• Passcode disabled: shows a clear passcode-required message.
• App backgrounding locks Key Manager again on return.
• Share Extension prompts biometrics for private-key operations.
Tested every iOS PGP app on the store. This is the one.Most of them are either abandoned, clunky, or make questionable architectural choices. This one gets the fundamentals right. Share extension instead of a Full access keyboard. That really matters. Keys stored in the Secure enclave. Keys.openpgp.org for key discovery is a great and seamless choice. Curve25519 and RSA both supported. The developer clearly knows what they're doing.I think the in-app public key lookup by email is what makes this usable beyond the hobbyist crowd. That one feature solves PGP's oldest practical problem.One genuine request: open source the code. I understand the hesitation. Someone might fork it, slap a new icon on it, rebrand, etc. That's a real concern and it's not fair. But being realistic about the market here, the people who need a serious PGP tool on iOS, actually understand what it does, and are willing to pay for it… that's not a huge crowd. Nobody is getting rich forking this. Meanwhile PGP is one of the most trust-sensitive tools a person can put on their device. We're handing it our private keys. For that specific category of app, the community needs to be able to verify what's actually happening. Nothing against the developer, he seems genuine. But PGP is one of the most trust-sensitive tools you can put on your device and “trust me” is the opposite of what cryptography is supposed to be. Since it’s a paid app a permissive license with attribution protection would keep credit where it belongs while giving users what they need.
