decentryk-qr 0.2.0

A package for combining and verifying QR codes using cryptographic hashes

DecentryK QR

A Python package for combining and verifying QR codes using cryptographic hashes.

Installation

pip install decentryk_qr

Usage

Command Line Interface

Combine two QR codes:

decentryk_qr combine --files qr_1.png qr_2.png

Verify two QR codes against stored hash:

decentryk_qr verify --files qr_1.png qr_2.png

Additional options:

# Specify output file for combined QR
decentryk_qr combine --files qr_1.png qr_2.png --output custom_output.png

# Disable hash storage
decentryk_qr combine --files qr_1.png qr_2.png --no-store-hash

# Specify custom hash file location for verification
decentryk_qr verify --files qr_1.png qr_2.png --hash-file custom_hash.json

Python API

from decentryk_qr import QRHashCombiner

# Create processor instance
processor = QRHashCombiner()

# Combine QR codes
combined_hash, hash1, hash2 = processor.process_qr_codes('qr_1.png', 'qr_2.png', 'output.png')

# Verify QR codes
is_valid, current_hash, expected_hash = processor.verify_qr_codes(
    'qr_1.png', 
    'qr_2.png', 
    stored_combined_hash
)

Features
