PGPony makes PGP encryption easy, private, and powerful, and every feature is free. Generate keys, encrypt to people or to a password, sign and verify, back up your whole keyring, and revoke compromised keys, all from your iPhone and iPad, in seven languages. New in 8.1.0: iPad support and large files. Encrypt, sign, and decrypt files of any size, including with an RSA hardware key over NFC or USB-C, with progress and cancel. Signing with a passphrase-protected RSA key is fixed. Post-quantum encryption pairs Ed25519 with ML-KEM-768, in RFC 9580 (v6) and LibrePGP versions, private even against future quantum computers. HARDWARE SECURITY KEYS Keep your private key on dedicated hardware, not your phone. Generate a key pair on the card over NFC, or add an existing card with a tap. Sign, decrypt, and encrypt-and-sign in one step, with RSA and ECC (Ed25519/Curve25519) keys, on YubiKey, Token2, and others. Full card admin: change or unblock PINs, factory-reset, and view Card Details. ENCRYPT, DECRYPT & SIGN Encrypt messages and files of any size to any public key, or to a password with no keys at all, readable by gpg -c and back. Decrypt with a private key, a hardware key, or a passphrase, now close to instant even with a large keyring. Sign without encrypting, including detached signatures and large files, and verify a downloaded file against its signature. A signature banner shows who signed on every decrypt, for every key type including RSA. AEAD (OCB) encryption. GENERATE & MANAGE KEYS Create keys on a card or in-app: post-quantum Ed25519 + ML-KEM-768 in v6 and LibrePGP, v6 Ed25519, classic Ed25519 + Cv25519, or RSA 2048/4096. Full OpenPGP v6 (RFC 9580), bit-for-bit interoperable with Sequoia PGP and GnuPG. A built-in helper helps you pick the right type. Import from files, clipboard, QR codes, or keyservers, including GnuPG v4 and v6 keys. Make revocation certificates and export private keys (GnuPG-compatible). BACK UP & RESTORE Save your whole keyring, secret keys included, as one encrypted file. A single backup code opens it, and the same file restores onto another iPhone or Android. The file stays with you, never on anyone's server. KEYSERVERS Look up a recipient by email through Web Key Directory, then keys.openpgp.org. Publish to several servers at once, and choose which PGPony searches and publishes to. Route lookups through Tor or a SOCKS proxy, and let background refresh catch revocations. PGPony warns when a server may not accept a newer key type. PASSWORD STORE Open a pass (password-store) folder and browse its entries. Decrypt with a software or hardware key, then copy the password through an auto-clearing clipboard. otpauth URIs are shown, and plaintext is dropped the moment you leave the entry. SHARE SHEET EXTENSION Encrypt or decrypt text, encrypt a file, or sign a file in any app: Safari, Files, Notes, Mail. Messages for your hardware key hand off to the app. SECURITY FIRST Face ID / Touch ID lock with auto-lock. Software keys live in the iOS Keychain (hardware-backed), or on an NFC card instead. iCloud Keychain sync, key expiration reminders, and Contacts auto-matching by email. No analytics, tracking, accounts, or sign-up. Your private keys never leave your device, and with a hardware key they never leave the card. SEVEN LANGUAGES English, German, Spanish, French, Japanese, Brazilian Portuguese, and Simplified Chinese. ALL FEATURES INCLUDED Everything is free with no restrictions: Post-quantum keys, on-card generation, and hardware keys (RSA and ECC) Cross-platform encrypted backup and restore, verified signatures including RSA Full OpenPGP v6 (RFC 9580), password encryption (gpg -c), multi-keyserver publishing with Tor Detached signing, Password Store, QR exchange, GnuPG import, open-source core, dark mode Built by an indie developer who cares about your privacy.
