Typage: Age Encryption with Passkeys
2025-07-16
Typage, a TypeScript implementation of the age file encryption format, now supports passkeys for enhanced security. Version 0.2.3 leverages the WebAuthn API for symmetric encryption using passkeys, offering phishing resistance. A companion CLI plugin extends this functionality to hardware FIDO2 security keys. The implementation utilizes the WebAuthn PRF extension, creating a per-file hardware binding and unlinkability. This allows for seamless encryption and decryption across devices, while maintaining strong security guarantees. The new `age-encryption.org/fido2prf` format is central to this improved security.
