Two-Factor Physical Bitcoins - Casascius

Want some personalized vanity addresses for your currency of choice? Check out Vanity Pool

I run a small project called Vanity Pool, it lets you outsource generation of cool vanity addresses through a split-key address algorithm - this means that your private key and thus your money is secure, even though other people mined for your address. This also means that you can get some nice vanity addresses and not have to spend a lot of your GPU time mining for the address instead of mining for your coin of choice.
So if you want some cool vanity address, like DDogeWowAA2EFcGmipzDjQBYQFXiqC8QFs or 1PiachuEVn6sh52Ez7o6Fymvw54qvQ4RBm , head on over to https://vanitypool.appspot.com/ , request a pattern you wish created (shorter patterns area cheaper and take a lot less time to generate), put in a public key that you own (you will need to use it later), when asked for network prefix, put in the decimal version of your coin-specific net-byte. Afterwards, you will be requested to pay a bounty in BTC (creating coin-specific pool would make the mining power a lot smaller; miners prefer being paid in BTC). After the payment is confirmed, any miner connected to the pool will start looking for the solution to your pattern.
Once you have the solution, either use Casascius' Address Utility, or head on over to our online tool (use coin-specific hex NetByte and hex Prefix Byte). After that you can import your new vanity address to your client by going through those steps (example using Dogecoin client).
Have fun!

[BOUNTY BONUS. Level: CODER] Review the source code for the Printer tool

Skills required: Github, C#
Clone the Github repo and dig into the source code in the Printer folder.
Note that there are a lot of forms in the Forms folder, but only "frmPrototype" and "TemplateEditor" are my original creations. All the others (which are not included in the Visual Studio Project file any more) are from the Bitcoin Address Utility project which this is built on top of. Equally, all of the really clever code in the Model folder, which does all the cryptography stuff, is stuff I inherited. Modifications were made to both the old forms and some of the Model classes to make that utility multi-coin-ready.
As with the request for code-review of the Loader tool, please check for signs of impropriety on my part. Of course I'm going to say "I haven't put anything in there to leak the private keys for your paper wallets" - consider this an invitation to get paid for looking!
Output: Please leave specific comments in this thread.
Reward: From Ð100 for comments which indicate you've had a quick look at the source, up to Ð2000 for greater depth and detail. Possibly even more, if you spot a big problem I hadn't thought of.

Dogecoin Wallet Import Format

Hi,
I'm trying to use the Bitcoin Address Utility to integrate some address generation in my C# app.
Unfortunately, my ignorance is getting the best of me. The utility generates addresses using a specified type (0 = bitcoin, 30 = dogecoin), and the public address resolves in dogechain eplorers but the Base58 string created from the private address starts with '5' and is 51 bytes, not 'Q' or 52 bytes, so I can't import them into my DOGE wallet.
What am I missing?

At the keys/addresses level, how does DOGE differ from BTC? (And, what's our Cointype value?)

Hi Devshibes,
I've decided to have a go at making a Dogecoin port of Casascius's Bitcoin Address Utility, and add in a couple of extra features along the way. (I'm a C# guy by background, starting to dabble in Android.)
I think one key Magic Number I need to look after is something referred to as "Cointype" in BAU's source (it seems to be 0 for BTC, 111 for Testnet, 52 for Namecoin and 48 for Litecoin). When I had a play with Doge Vanity Addresses, I was instructed to pass in a "version" value of 30 - is that it?
Are there any other things I should be aware of at the keys/addresses level of activity? I'm not intending to touch the blockchain - just have a damn good play with paper wallets and see if I can come up with something useful.
