CypherAir is a fully offline, open-source OpenPGP encryption tool built for iOS, iPadOS, macOS and VisionOS. It makes zero network connections. There is no telemetry, no tracking, and no possibility of data leakage.
Two Encryption Profiles
• Universal (Profile A) — Interoperable with GnuPG and all major PGP implementations. RFC 4880 compliant, employing Ed25519 and X25519 with SEIPDv1.
• Advanced (Profile B) — Implements the latest OpenPGP standard, RFC 9580, with Ed448 and X448, authenticated encryption via AEAD (SEIPDv2), and Argon2id passphrase protection.
Capabilities
• Encrypt and decrypt text and files, processed as streams for efficiency
• Create digital signatures — cleartext for messages, detached for files
• Exchange public keys through QR codes using the system Camera, with no camera permission required
• Manage multiple keys, each with its own encryption profile
• Safeguard private keys in the Secure Enclave, unlocked only by Face ID or Touch ID
Privacy Through Architecture
• The sole system permission is the Face ID usage description
• Private keys never leave the protection of Secure Enclave wrapping
