nuft-cli

A zero-dependency terminal utility to instantly compute valid core banking cryptographic webhook signatures from local transaction layout files.

Installation

pip install nuft-cli

Usage

Create a mock transaction object file named webhook_data.json:

{
  "transaction_id": "TXN-9021104",
  "amount": 25000,
  "currency": "NGN",
  "status": "success"
}

Execute the hash generator tool from your terminal prompt, passing the data file along with your provider endpoint configuration secret:

nuft webhook_data.json --secret my_mock_provider_secret_key

The console will instantly print a normalized string output map alongside standard financial digest signatures, allowing you to quickly construct mock headers for Postman, cURL, or local automation scripts.
