iPGMail vs PGPony

iPGMail is a complete OpenPGP client for iPhone and iPad. Encrypt, decrypt, and digitally sign email and files using the same RFC 9580 / RFC 4880 standard you already use with GnuPG, Mailvelope, Thunderbird, ProtonMail's PGP exports, and any other OpenPGP-compatible tool. Bring your existing PGP identity to iOS or generate a new one in the app. Your private keys are stored in a private local database with the highest data-protection class and are unlocked only by Touch ID or Face ID. All cryptography runs locally — your keys and message content never leave your device. CRYPTO & INTEROPERABILITY • OpenPGP v4 and v6 (RFC 9580 / RFC 4880, RFC 6637) — fully interoperable with GnuPG, Mailvelope, Thunderbird, ProtonMail PGP exports, and any other compliant tool • Public-key algorithms: RSA, DSA, ECDSA, EdDSA (Ed25519, Ed448), ECDH (Curve25519, X448) • Symmetric ciphers including AES-256, with modern AEAD encryption on PGP v6 (SEIPDv2) messages • PGP/MIME for encrypted email; standard ASCII-armored output for any plain-text channel • Detached and inline signatures; sign-only mode for authenticated but readable messages • Symmetric (password-based) file encryption • Encrypt to multiple recipients in a single message EMAIL • Send encrypted email directly from the app via SMTP — works with iCloud, Gmail, Outlook / Hotmail, Yahoo, AOL, Fastmail, GMX, Yandex, mail.ru, QQ, Comcast, and any custom SMTP server • Google OAuth2 for password-free Gmail authentication • Reply with quoted plaintext ("> " prefix) so encrypted threads read like normal email • Or hand off to your default mail app via the standard iOS share sheet KEY MANAGEMENT • Generate new keypairs in-app with strong defaults (ECC or RSA) • Import existing public and private keys (ASCII-armored or binary) • Search SKS / hkps key servers and Keybase to find recipient keys • Attach your public key to outgoing messages so recipients can import it directly • Inspect key flags, expiration, signatures, and user IDs FILES • Encrypt and decrypt files up to 100 MB per file (200 MB total per message), with on-screen progress • Quick Look preview of decrypted content in-place • Receive encrypted attachments directly from iOS Mail.app — no copy/paste required • Read .pgp, .gpg, .asc, and .sig files from anywhere via the Files app, AirDrop, iCloud Drive, Dropbox, or the system clipboard • Open URL handler for the x-ipgmail:// scheme so other apps can hand work to iPGMail iPAD-OPTIMIZED • Sidebar navigation and full keyboard shortcut support • Optimized layouts for Split View and Stage Manager PRIVACY POSTURE • Private keys are stored locally in a secured private database and unlocked only by Touch ID / Face ID • All encryption, decryption, signing, and verification happens on-device • No account creation, no cloud middleman, no third-party access to your message content • Open standard — your keys and messages stay portable to any other OpenPGP tool, on any platform WHO IT'S FOR Built for journalists, activists, security professionals, lawyers, developers, and anyone who already uses PGP on the desktop and wants the same workflow on iOS. Bring your existing key, decrypt your inbox, sign and send — without surrendering custody of your keys to anyone.

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. Your keys, your messages, your data, always yours. Terms of Use (EULA): https://pgpony.app/eula.html Privacy Policy: https://pgpony.app/privacy.html
