Picocrypt NG developers ✓ Verified
io.github.picocrypt_ng.Picocrypt-NGPicocrypt NG is a small, simple, yet very secure file encryption tool. It uses XChaCha20 for encryption and Argon2id for key derivation, with optional cascaded Serpent encryption in paranoid mode.
Features include Reed-Solomon error correction for data recovery, keyfile support, volume splitting, and a full command-line interface for scripting and automation.

2.1617 Jun 2026
- Release artifacts are signed with keyless cosign and a GitHub build-provenance attestation
- Desktop: advanced-settings tooltips no longer flicker or jump
- Android: key material is zeroed after use, saved file names are sanitized, and cloud backup is disabled
- Privacy: the app no longer writes log files to disk
- Reliability: incomplete output is cleaned up if an operation is interrupted mid-stream
2.1516 Jun 2026
- Android: encrypt a whole folder or multiple files at once, with a new Compress toggle
- Android: optional screenshot protection (FLAG_SECURE) that also hides the app in recent apps
- Cross-platform passwords are normalized to Unicode NFC so non-ASCII passwords work across operating systems
- Android: smaller per-architecture release APKs alongside the universal APK
- Linux: the AppImage is GPG-signed and ships delta-update (zsync) info
2.1414 Jun 2026
- The compression and deniability passes now report speed and ETA
- Reed-Solomon decoding rejects malformed input instead of panicking, and a split size that would overflow is rejected before encrypting
- Android runs long operations in a foreground service and adds a verify-first decrypt option
- New Linux AppImage package
2.1312 Jun 2026
- Late Finder/AppKit batches of one open gesture on macOS extend the already-applied iCloud selection instead of replacing it
