AgePony

AgePony is an encryption app for Android built on the age file encryption format. It encrypts and decrypts files and text, signs and verifies them with SSH keys, and generates post-quantum hybrid keys. Everything runs on the device: no accounts, no servers, no analytics.

Features age encryption and decryption for files and text, byte-compatible with the age CLI Post-quantum hybrid recipients (ML-KEM-768 + X25519), encoded as age1pq1... keys Passphrase encryption using scrypt recipients Encrypt to SSH public keys (ssh-ed25519, ssh-rsa) Sign and verify with SSHSIG, using software Ed25519 keys, Android Keystore hardware keys, or a FIDO2 security key over NFC Multi-file tar bundling, so a set of files travels as one signed and encrypted archive Migration flow that batch re-encrypts existing files to a quantum-safe key, keeping originals until the new copy verifies Recipient and identity vault, encrypted with a Keystore-backed master key and gated by biometrics QR scanning and display for exchanging recipient keys ASCII armor support
