AgePony is an open-source Android encryption application designed to secure files and text using the age encryption format. It supports encryption and decryption compatible with the age command-line utility, including passphrase-based protection. Users can generate post-quantum hybrid keys combining ML-KEM-768 and X25519 cryptography. Private keys can be protected through Android Keystore hardware, biometric authentication, or compatible YubiKey devices. The application supports SSH-based digital signatures, signature verification, and trusted signer management. Additional tools include encrypted key vaults, QR-based key sharing, secure device-to-device transfers, and multi-file archives. AgePony operates locally without accounts, external servers, or analytics, keeping encryption operations under user control.
