Picocrypt-NG Protégez votre Smartphone application pour Android description
Picocrypt-NG encrypts files locally — a community-maintained continuation of Picocrypt. No accounts, no cloud, no telemetry, no network access (the app does not request the INTERNET permission).
XChaCha20 for encryption, with the key derived from your password by Argon2id. Every volume is authenticated, so tampering or corruption is detected on decryption.
Features:
- Encrypt a single file, multiple files, or a folder
- Optional keyfiles, with an option to require them in a fixed order
- Paranoid mode: extra cipher cascade and harder key derivation
- Reed-Solomon error correction to recover volumes from limited corruption
- Deniability mode: the encrypted volume appears as random data
- Optional compression
- Comments stored with the volume
- Optional verify-before-write integrity check
- Long operations continue in a foreground service when the app is backgrounded
Volumes are cross-platform with the desktop app (Windows, macOS, Linux). A multi-file or compressed volume contains a single .zip inside; Android saves it without extracting.
Free software under GPLv3. The Android app is built from source: the native library is compiled from the Go sources in this repository, with no prebuilt binaries committed.
