Well from the information being sent back to a PHP server in itself UNENCRYPTED IN ANY WAY gives me cause to call this a SCAM or a SECURITY RISK.

https://github.com/RobKohr/print.printcoins.com/blob/master/index.php

USE AT YOUR OWN RISK FOLKS!

You realize that you can run both scripts locally, don't you?
bitaddress.org just needs to be saved as HTML to run locally and print.printcoins.com can be run on a localhost apache server because you have the source code available and you are free to use it.

You can say it's a security risk but you can't call it a scam. And the OP clearly says you can run the code yourself and don't have to trust him, so, I still can't understand what's your beef...
You can always do something better yourself and give it to the community. Aren't you a programmer?

I am a programmer but not EVERYONE is a programmer. You need to develop tools like this for the MASSES. The ones that have NO CLUE how to set up an Apache server.

So, being a programmer you can develop one of those tools for the masses. Why not?
It's easier to just say what others do isn't good enough instead of improving it?

I thought Mike was going to be doing a plugin for bitaddress.org but instead he did a desktop solution. Do you know if he still plans on doing a bitaddress.org solution?

I'm trying to convert one of the svg layers which is a png into a pure vector so he can change the color programatically. I think the idea is to provide a pure js version using a SVG file of my design.

But it's not being easy to get that specific layer on vector format.

I am completely fine with a NON ARTSY solution.

So far, I have loading the SVG into an iframe and updating the address/key in JS.
I will load the SVG externally because 4MB of data per artwork is too much to embed or download on initial load. Also, this makes it easier to incorporate other designs.
I will put some thought into signing the final SVG because it can include JS.

Next step for me is getting a QR code into SVG format... or use CSS positioning.

Wow, didn't think this would go down the scammer territory path. For those who wish to view the source code, but want to get right to the meat of where the action is:

https://github.com/RobKohr/print.printcoins.com/blob/master/index.php

This is where I wrote all of the code, everything else is just library stuff. Nothing writes to a file. Nothing writes to a db. It takes in input, and spits back a pdf. Yep, it is http, rather than https. If anyone wants to buy me a cert for this one off project, I'll take it Otherwise you will have to consider a possible man in the middle attack.

The reason this is server side rather than js is that I have not found one decent pdf creation library written in javascript (just a couple half hearted attempts that were useless). pdf's are the simplest way to create something that will print to exact dimensions on the web.

If you have no faith in me, then download it and run it yourself, that is what the code is for. The website is just up there so you can be lazy if you trust me. I would be more worried if someone created an executable to do this on your home machine, as that would be able to get to your actual wallet. Or just don't use it at all. 

As far as the actual usefulness of bitcoin bills, well that is a good question. It could be handy for off the grid transactions where both parties trust each other. I find that most people use them as gifts or as a way to sell bitcoins to others as an investment, but where the other person just doesn't want to bother with setting up the tech to handle bitcoins. For real commerce in physical form off the grid with untrusted parties, significant steps would need to be taken to prevent counterfeiting as well as private key extraction. Right now, I think only Casascius has a product that I would accept as money from a stranger on the street. It would be difficult and expensive to forge that product. When bitcoin is common enough to easily find merchants in meatspace to do transactions with, I think there will be plenty of physical forms out there. Cash is a much more natural for exchange than two people tapping on their cell phones and then waiting for the transaction to be verified. It is also much more satisfying to be paid in cash, and more untraceable (for both bitcoins and fiat).

if it only needs to be run on a bare server with php, then a lot of the editors include a preview mode that should work, get a php editor that has a preview (i use 'php expert editor' first and only one i've tried) install php(might have to set the path to php in the editor options), open script, audit script, run script, done

[PrintCoins]

I just added Psy's design. Take a look at it here:

Note: By the way, do not use this set of bills generated by this url. They are using private keys that will be available to all. Go to http://print.printcoins.com to generate your own.

Just tried this on your site, unfortunately I got this error:

Thanks rate5, all fixed.

[odolvlobo]

I tried print.printcoins.com and it worked for each of the designs until I tried turing. Then it only displayed a half-finished loading icon. Now no matter what I do, that's all I get.

[QuantumKiwi]

I just had an awesome laugh at the troll moronic newbies yelling and screaming that data is being stored on the server.

Why is it open source?

You call us the fools yet you could easily run a local webserver, closed from internet acccess and still - no data will be recorded.

Amazing to see the amount of intelligence patiently combating the idiots. Well done

Btw, Im going to put this into use here in NZ. Many people will be interested, especially seeing it on paper...

[Than Jolg WI]

I like this service! How about a really minimalistic design too? Like the one bitaddress.org has. Could be useful if you want to take a paper backup of thousands of addresses.

@robkohr - hey just a quick note to say I think this is a pretty darn great start, and it's very kind of you to make this an open source and apparently noncommercial project. I also appreciate that your webpage has end-to-end instructions, including where to buy security holograms which is a nice touch.

For those crying spam/fraud/etc. the only fault of robkohr is that he didn't specify up front that this code has the potential for air-tight security by being run on local servers, and/or converted to javascript and run over SSL, etc. On the other hand, anyone crying 'scam!' should be smart enough to know that the current online version is a proof of concept, a starting point us to try out some small conversions -- clearly not a clearinghouse where anyone should dump hordes of coin. I believe robkohr's intentions are pure, but it would be silly to trust large amounts of coin with an unencrypted website on a webhost which may or may not be compromised by hackers. (Dollars to donuts, I'll bet hackers are trying to compromise printcoins.com right now since it's probably easy pickings.)

Here's what I love about printcoins:

* converts bitcoins to a tangible exchange, which makes it possible to engage ordinary citizens in bitcoins not just übernerds. For example, some workers are in my backyard right now are building me a chicken coop. They don't know squat about bitcoin. But I could probably pay them in bitcoin if I had a nice looking bill in my hand and explained to the foreman, "hey, if you're a gambling man, I'll pay you 25% in this very weird currency which has increased in value a few hundred percent in just a few months. Just hold onto this bill and don't lose it, and here's how you use your cell phone to see what it's worth from time to time."

* (once run on a local server) doesn't require trusting anyone with your wallets/addresses. I've loved the idea of buying Casascius coins, but I just can't get over my paranoia stemming from the fact that criminals have a huge motivation to insert themselves into the minting process. I don't just mean hackers, I mean people physically breaking into the minting premises and causing mischief.

What printcoins represents is a huge step towards easy distributed "minting" which is really the key to using bitcoin without putting your bitcoins online where hackers are trying -- and succeeding -- to steal them.

Thank you for your praise caton, it is greatly appreciated. If anyone would like to support paying for a vps and a cert, I can make this more locked down for everyone. Of course, you still have to trust me. The best remidy to that is to run this yourself.
