tokn-nautrw 1.0.0

CLI tool to store TOTP secret keys and generate codes

tokn

Tokn is a CLI-based TOTP (time-based one-time password) code generator that uses encryption to store secret keys.

Quick Start/Installation

From GitHub

1. Clone the GitHub repository or download the code (using the green button)
2. Inside the directory, run the following command (you may need to add python -m or python3 -m before it):

pip install -e .

Features

• An encrypted vault file used to store keys
• Secret keys and passwords are never exposed
• Accounts can be added via QR code screenshots, raw codes, or URIs
• CLI is designed to be as ergonomic as possible

Advanced

• The vault is stored in their best location depending on the operating system:

Linux: /home/USER/.local/share/tokn/keys

MacOS: /Users/USER/Library/Application Support/tokn/keys

Windows: C:\Users\USER\AppData\Local\nautrw\tokn/keys

• Commands are split among several files in tokn/commands, and imported back into tokn/cli.py to be added under the cli command group, allowing for commands like tokn add
• A pyproject.toml file is used for treating the project as a package, allowing the use of pip install -e . and uploading to PyPI in the future
• The cli function in tokn/cli.py is what gets run; it is specified in the [project.scripts] section in the file

Technologies/libraries used

• The pyotp library is used to generate the TOTP codes as specified in RFC 6238
• The cryptography library, specially fernet, is used to encrypt files
• Argon2, as implemented by the cryptography library, is used to generate password hashes that are used as keys for fernet
• The click library to make it a CLI app
• The zxingcpp and opencv libraries for QR code scanning
