Mage

Android GUI for age file encryption, built on kage.

New in version 0.1.3

Drops the network-state permission: it was pulled in by an unused
part of the camera library and Mage never needed it.

Mage is an Android GUI for age file encryption, built on kage (a Kotlin/JVM implementation of the age protocol). "Mage" is short for Mobile age. Mage is not officially affiliated with or endorsed by the age project.

Encrypt or decrypt files to age recipients or passphrases, including armor, multi-recipient, and encrypt-to-self. SSH keys (ssh-ed25519, ssh-rsa) work as recipients and identities alongside native age keys, and can be mixed on one file.

Identities are sealed in the Android Keystore (AES-256-GCM, StrongBox where available) behind biometric or device-credential authentication. Recipients get a small address book with QR encode/scan for sharing a public key.

Batch mode encrypts or decrypts more than one file at a time into a folder. Your identity vault can be exported and re-imported as an encrypted backup, so it isn't stuck on one device.

Mage hooks into the system where it makes sense: share-sheet targets, a .age file-manager association, launcher shortcuts, and a Quick Settings tile.

Mage does not implement its own cryptography — that is kage's job. It is not a general-purpose file manager or password manager, and it does not support the age-plugin mechanism, which relies on binaries on $PATH and does not work on Android.

Mage requests no network permission and makes no network connections.

New in version 0.1.2

Fixes the floating nav bar covering bottom controls on some screens,
improves biometric unlock support on older or budget devices, and adds
a recovery path if a biometric change invalidates the vault key.
Encryption is now more reliable on non-standard storage backends, and
copied private keys are hidden from clipboard history.
