PGPony vs CypherAir

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 eleven languages. New in 8.4.0: pairing with PGPony Desktop, key certification, Ed448 keys, a PGPony PIN, and Korean, Turkish and Ukrainian, with every screen translated. POST-QUANTUM Encrypt with ML-KEM-768 or ML-KEM-1024 paired with X25519, and sign with ML-DSA-65 paired with Ed25519 (RFC 9980), on RFC 9580 (v6) keys or the v4 shape GnuPG 2.5 reads. Add post-quantum subkeys to a key you already have. HARDWARE SECURITY KEYS 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, over NFC or USB-C. Full card admin: PINs, factory reset, and Card Details. ENCRYPT, DECRYPT & SIGN Encrypt messages and files of any size to one or many public keys, or to a password with no keys at all, readable by gpg -c and back. Pick which subkey to encrypt to when a key has more than one. Decrypt with a private key, a hardware key, or a passphrase, and see which of your keys opened the message. Sign without encrypting, including detached signatures, and verify a file against its signature. GENERATE & MANAGE KEYS Create keys on a card or in-app: post-quantum, v6 Ed25519, classic Ed25519 + Cv25519, or RSA 2048/4096, with or without an email address. Add, revoke, or remove subkeys (including authentication subkeys) and User IDs. Full OpenPGP v6 (RFC 9580), interoperable with Sequoia PGP and GnuPG. Import from files, clipboard, QR codes, or keyservers. 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 iPad. The file stays with you, never on anyone's server. KEYSERVERS Look up a recipient by email through Web Key Directory, then key servers. Add your own servers, publish to several at once, and upload an updated key straight from Key Detail. Route lookups through Tor or a SOCKS proxy, or turn on offline mode to stop every network request. PASSWORD STORE Open a pass (password-store) folder, decrypt an entry with a software or hardware key, and copy it through an auto-clearing clipboard. SHARE SHEET EXTENSION Encrypt or decrypt text, encrypt a file, or sign a file in any app: Safari, Files, Notes, Mail. SECURITY FIRST Face ID / Touch ID lock with auto-lock. Software keys live in the iOS Keychain. Keys and messages from outside are checked strictly before they are used. No analytics, tracking, accounts, or sign-up. Your private keys never leave your device, and with a hardware key they never leave the card. ELEVEN LANGUAGES English, German, Spanish, French, Japanese, Korean, Brazilian Portuguese, Russian, Simplified Chinese, Turkish, and Ukrainian. Built by an indie developer who cares about your privacy. Your keys, your messages, your data, always yours.
