## What is WispPGP?

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.

Armored exports include clear headers: Version: WispPGP, Comment: https://micro.mjanssen.nl/wisppgp

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.

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.

### 3/5 — Doesn’t Work

*2026-07-04*

The app freezes on launch on my iPad. Works fine and looks good on my iPhone though. Will give 5 stars if fixed.

Info:

iOS 26.5
iPad Pro 13-inch M5

When I open the app, it freezes and says: 

“No private keys. Add or import one in Key Management.”

and 

“Temporary max brightness is active for easier scanning.”

**Developer response:** Hi Dylan. That’s a shame to hear. I don’t see these problems on my end. Will try to reproduce

### 5/5 — Best PGP app on iOS

*2026-05-14*

I've tried a few pgp apps, and this is easily the best one on iOS. Everything just works, not overly complicated. One of its best virtues is its developer. I had suggested a feature, and within days he had pushed out an update addressing it. Easily the best experience I've had with a pgp app, or really any app, on iOS.

**Developer response:** Thanks Nyrlover, for your kind words.

### 5/5 — Great PGP app!

*2026-04-01*

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.

**Developer response:** Thanks for the nice review.

### 5/5 — Beautiful interface

*2026-03-18*

Lovely looking app hope it works as well as it looks 😁

**Developer response:** Thank you. Hope you enjoy the app

### 1.2 — 2026-04-21

# WispPGP 1.2 — QR, scanner & landscape visit card

**Tip:** When you **rotate the iPhone or iPad to landscape** (long edge horizontal), the app shows a full-screen **visit card** instead of the usual tab bar. Rotate back to **portrait** for Encrypt / Decrypt / Sign / Verify / Settings.

## Public key QR (Key Management)
- **openpgp4fpr QR**: From key details, open **Public key QR** to show a QR code whose payload is the **`openpgp4fpr:`** URI (OpenPGP v4 fingerprint)—same standard as keyserver-oriented sharing.
- **Copy & share**: Copy the **URI** or the **QR as an image** to the clipboard, use the system **Share** sheet, and read short guidance about keyservers (e.g. keys.openpgp.org).
- **Monospaced URI** on screen with text selection for manual copying.

## Scan QR (import fingerprint)
- **Scan QR** in Key Management uses the **camera** (VisionKit `DataScanner` where supported) to read a QR payload.
- Valid payloads are **`openpgp4fpr:`** URIs; the fingerprint is queued for import in Key Management. Invalid codes show a clear error.
- On unsupported devices or without camera access, the app explains the limitation.

## Landscape visit card (identity)
- **How you get there**: **Turn the device to landscape orientation**—the main UI is replaced by a single full-screen **visit card** (fingerprint identity + QR). This is **only** in landscape; it is not shown in portrait.
- **Landscape-only UI**: The tab bar and tab content are hidden; **portrait** restores the normal tabs and all features as before.
- **Same openpgp4fpr idea**: The card’s QR encodes **`openpgp4fpr:`** for the identity of your **currently selected private key**.
- **Public key first**: If a **public** key with the same OpenPGP key ID exists in the vault, that material is used (no biometric prompt). Otherwise the **private** key is used (Face ID / Touch ID when required).
- **Layout**: Wide landscape card—accent strip, **headline** (prefers the **public key’s name**, else the **private key’s name**, else “Active private key”), `openpgp4fpr` label, URI, optional user ID, QR on the side.
- **Save to Photos**: Button to save the visit card **as an image**; iOS may ask once for **photo library add** permission (`NSPhotoLibraryAddUsageDescription`).
- **Placeholders**: Clear messages if there are no keys, nothing selected, unlock cancelled, read errors, or fingerprint issues—no empty card.

## Localization & permissions
- Strings for QR flows, scanning, landscape card, save actions, and photo access are covered across **all supported app languages**. Camera use for scanning is described in `NSCameraUsageDescription`.

## Technical
- QR bitmap generation supports multiple **error-correction levels** where useful for reliable encoding of `openpgp4fpr` payloads.
