Editor's Overview

PGPony is a password & 2fa application developed by NorseHorse, packaged as a single Android APK of version 4.4 weighing in at 14.88 MB. The package targets Android 4.1+ and above. Below you'll find the publisher's own description, a quick spec sheet, and a short buyer-beware checklist so you know exactly what you're installing before tapping download.

Install Checklist

  1. Only download through the button on this page — never from third-party mirrors or shortened links, which are the most common way malware spreads.
  2. File size is a light 14.88 MB, so it installs quickly even on modest connections.
  3. This build is signed by "NorseHorse" — always verify the developer name matches what's listed on the app's official store page before installing an update.
  4. After install, Android may prompt you to allow "Install from unknown sources" — approve only this one install, then revoke the permission in Settings > Apps > Special access.
  5. We link directly to the APK file or the publisher's repository; we do not modify the binary. Always run a virus scan after any sideloaded install.

About this app

PGPony is an OpenPGP app for Android. Encrypt, decrypt, sign, and verify messages and files, manage your keyring, and use a hardware security key over NFC, all on device.

Features:

- Encrypt, decrypt, sign, and verify text and files
- Post-quantum encryption: ML-KEM-768 + X25519 (Kyber) composite keys, in both the IETF draft (v6) and LibrePGP / GnuPG 2.5 (v5) formats
- OpenPGP provider service: use PGPony as the crypto engine for Thunderbird for Android, K-9 Mail, and Password Store (OpenKeychain-compatible API)
- Generate modern keys, including RFC 9580 (OpenPGP v6) Ed25519 and X25519, with Argon2id passphrase protection
- Hardware security keys over NFC, including YubiKey 5 NFC and Token2, with on-card key generation, decrypt, sign, PIN management, and factory reset
- Read your password-store (pass) entries, including those protected by a hardware key
- Encrypted keyring backup and restore, including OpenKeychain backup import
- PGP/MIME email: decrypt messages with attachments, compose encrypted .eml
- Key discovery through WKD and the keys.openpgp.org verifying keyserver; optional Tor routing via Orbot
- Optional contact integration for choosing recipients
- QR import and scanning for keys
- Default signing key, biometric lock, and secure-screen protection

Post-quantum limitations:

Post-quantum OpenPGP is still being standardized, so cross-tool support is limited:

- LibrePGP-format (v5) keys interoperate with GnuPG 2.5+ today: messages encrypt and decrypt in both directions, and public keys import cleanly. GnuPG cannot yet import post-quantum PRIVATE keys from any app — it stores them in a proprietary internal format.
- IETF-format (v6) keys implement draft-ietf-openpgp-pqc and are verified against the draft's official test vectors, but current Sequoia (sq) preview builds implement a different draft revision and cannot read them yet, and GnuPG does not support this format at all.
- Classical keys (RSA, Ed25519, v4 and v6) are unaffected.

PGPony does not use accounts, ads, analytics, or tracking. The F-Droid build contains no Google services and runs fully on de-Googled devices.

The cryptographic core is published separately as open source (PGPonyCore-Kotlin), and the full app source is available under the Apache-2.0 license.

Frequently Asked Questions

Is PGPony free to download?
Yes. The APK file linked from this page is free. The developer may offer in-app purchases once installed, but obtaining the installer itself costs nothing.

What Android version does PGPony require?
Android 4.1+ or newer. Installing on older devices may cause crashes or refuse to install.

Is PGPony safe to install?
We link to the exact APK published by NorseHorse. We do not modify the file. Still, as with any sideloaded app, scan it with a reputable antivirus before opening it, and only grant permissions the app genuinely needs.

How do I update PGPony?
Install the newer version on top of the old one — Android will keep your data. If the signature differs, uninstall first (you may lose local progress).

Why is the app not installing?
Common causes: not enough storage, an older Android version than 4.1+, or a conflicting build already installed. Free up space, check your OS version, and uninstall any previous copy before retrying.
