Quickhash is developed in my own time and the website costs are paid from my own pocket. Like many of us, I have family commitments and work commitments to juggle around its development. If you value the program at all, I’d value a PayPal donation. As much or as little as you like and hit the donate button and you’ll be taken to PayPal website. Or, visit https://paypal.me/quickhash. Thank you!
