App Description
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 the iOS Keychain 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 (Curve25519, Curve448, 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,
