cryptfs-cli

cryptfs-cli is a cross-platform command-line tool for creating, mounting, and unmounting encrypted repositories using GPG for passphrase management. gocryptfs (Linux), and cppcryptfs (Windows) are used as backends.

Features

Cross-platform: Runs on both Linux and Windows.
Flexible Encryption: Uses gocryptfs on Linux and cppcryptfs on Windows.
Secure Passphrase Management: Leverages GPG for passphrase encryption. Combined with OpenPGP-compatible smart cards like YubiKey, the security is ensured.
User-friendly CLI: Built with the Cobra library for comprehensive help and documentation.

Installation

Prerequisites

Ensure the following tools are installed and accessible in your system’s PATH:

Linux: gocryptfs, gpg, fusermount
Windows: cppcryptfs.exe, cppcryptfsctl.exe, gpg (from Gpg4win)
