Age Vault vs Silk Script Runner

ENCRYPT WITHOUT TRUSTING ANYONE. Age Vault is a modern, on-device encryption app for iOS. It implements the open age specification — the same cryptography used by security professionals as a simpler, more auditable alternative to PGP. No servers. No accounts. No analytics. Your private key is generated on your iPhone and never leaves it. — WHAT YOU CAN DO — • Generate an X25519 keypair, locked behind Face ID • Encrypt text messages to anyone whose public key you have • Decrypt messages sent to you with a tap • Save recipient public keys as named contacts • Encrypt files — photos, documents, archives, anything • Send the same encrypted payload to multiple recipients at once • Export and back up your keypair through the iOS Share Sheet — HOW IT WORKS — Age Vault uses the open age encryption format: • X25519 elliptic-curve key exchange • ChaCha20-Poly1305 authenticated stream encryption • HKDF-SHA256 key derivation Encrypted output is the standard age format, interoperable with the reference age CLI on macOS, Linux, and Windows. You are not locked into our app. — PRIVACY POSTURE — • Zero data collection. No analytics SDKs, no crash reporting off-device, no advertising IDs. • No backend. The app has no server it talks to. • Keys live in the iOS Keychain. We have no copy and no recovery — by design. • Face ID authentication is handled by Apple's LocalAuthentication framework. Your biometric data never enters our code. • In-app purchase is processed by Apple's StoreKit. We see only a confirmation that a valid purchase exists. Full privacy policy: https://dolucid.com/age-vault/privacy.html — FREE vs. PREMIUM — The free tier is fully usable for encrypted messaging: • Generate keypair • Encrypt and decrypt text messages • View your public key A one-time $2.99 unlock adds: • File encryption (any file type) • Contacts vault — save recipient keys with names • Multi-recipient encryption — encrypt once, share with many No subscription. No recurring billing. One purchase, yours forever, restorable on any device signed into your Apple ID. — WHY AGE? — PGP is powerful but notoriously difficult — long key IDs, web-of-trust ceremony, dozens of legacy options that hide footguns. Age was designed by security researchers as a modern replacement: small key format, no configuration, no algorithm choices to get wrong. — OPEN SPECIFICATION — The age format is published, peer-reviewed, and implemented in multiple languages. Anything Age Vault encrypts can be decrypted by the reference age tool on a desktop. You own your data and your encryption keys, in a portable format.
