This PR updates the ssh-otp.py script to ensure compatibility with both Python 2.7 and Python 3, removing the dependency on the yaml library. The script now uses a minimal internal YAML loader/dumper for configuration, and includes a default fallback mechanism if configuration loading fails.
Details:
Ensures the script runs seamlessly on both Python 2.7 and Python 3.
Removes the need for the external yaml dependency.
Adds a minimal YAML parser and dumper within the script for basic key-value configuration.
Implements a default configuration fallback if loading fails, improving robustness.
Updated QRCode URL which had been discontinued
No changes to the user-facing interface or command-line usage.
Motivation:
This change improves portability and ease of use, especially on systems where installing extra Python dependencies is not desirable or possible.
