The encryption library I wrote for shits and giggles
by

on 23/12/2011, 22:27:56 UTC
So I made this library just to teach my self more about cryptography, so if decryption without the key is as simple as multiplying by 3 and dividing by 2, that is expected.
I would appreciate any and all feedback on its workings, its an eclipse project, where the example encrypts 2 bytes and then decrypts them.
Just to save my own ass here in case some nut job tries to use it to actually secure something, I reserve full rights to this code and any code that does the same thing to the full extent of my rights. Any unauthorized use is prohibited, with the exception of figuring out how it works.
Thanks for taking a look at it (I know the hashing/key deriving function is most likely insecure, but I'm no expert).
And yes, this code is ugly, but that because the only thing I use java for is that first step from psuedocode to c++ or whatever is appropriate.
I assume no responsibility for any eye burning as the result of reading this code.
(Shout out to David Schwartz for helping me fix one of my ADHD induced code-holes on stack overflow)

Re: Printing Bitcoin Bills
by

I'm just wondering, without a trusted third party, how can someone trust the maker of these bills that the private key is really under the hologram?

Impossible to know. When you buy physical bitcoins off someone you are putting your trust into them.

The code to create the PDF will automatically generate the keypair and put the QR codes into the bill. It would take modifying the code to remove the private key. Though the printer could also scan the private key themselves to steal them (or also modify the code to make it record them).

That said, when the details of the algorithm are solid and can be translated into php or a bash script, I will be incorporating 3rd party private key addition to the bills (you would print a sheet, sticker it, send it to someone else to print over keypair two and they would sticker and cut it).


So what you're saying is there is no guarantee to their value, which makes them essentially worthless by virtue of being totally unreliable. good job.

They are as reliable as the person that prints them. This is the nature of physical bitcoins.
Here is one of those coating the toast with gold things.
You could act as a trusted 3d party that they send their bitcoins to, and you can ensure the bills are funded.
+1 great idea!  or make it so people can check the balance of the bill.  or can you already do that?
You can do that by putting the public key/address into block explorer.
The problem is that printing bitcoins is easy, I have had a script to do it sitting in my home folder for quite a while.
If i wanted to, after he started selling his fancy script, I could just release my script for free and crash his business.
There is also the problem of trust, if any one can just buy a kit and print them, then you know someone is going to make a lot with public keys that don't correspond to the private key and then sell them for free money.
The solution is you sell your services as a trusted third party, they do the printing, get the bills just like they like them, then you check to make sure the private keys correspond to the public keys and put your signature (or some better identifying mark) only on the ones that do, then you send them back, they fund them and put the holograms on. Then the people can rest assured that because your mark is on the bill, that the address on the bill corresponds to the private key under the hologram.

You can create dead man switches that will take care of your Bitcoins if you or your loved ones are physically coerced.
Easy way: Buy flash drive+fingerprint scanner
Hack together the two devices in such a way the fingerprint scanner does nothing.
Tell them you  have to do it because the fingerprint scanner has advanced biometrics and can tell when you are stressed.
Step on flash drive.

Re: Can bitcoin save the world?

Computers for everyone. How will 3rd world countries get,earn,mine for bitcoins if they don't have computers?
How do people in 3rd world countries mines gold,oil, or other resources? The poor of any country will be left behind in the digital age much like they have been left behind currently. Near the end of the Roman empire, the top 1% owned over 16% of all the wealth, today in America the top 1% own over 40%.....

Are this stats realistic? Really?
I'm almost hesitant to doubt them.
The only one of those I know is true is that if you have spare money in the bank, you are among the worlds top 8% in wealth.
Me goggling while writing my post: Its actually 38 some percent of the wealth belong to the top 1%, so some projections might place it over 40.
Honestly, I think bitcoin might be the enabler that allows the lower classes to jump that gap.
As it stands, you need alot of money to get involved in high finance.
With bitcoin, you have just as much control over those bits as he does. You are free to put every single one where ever you want.

So your charging money for something i can do for free with scripts you can find if you Google hard enough (and on my black an white laser printer?)?
I'm not saying that this is a stupid idea, it is just not the best idea to try to sell something that is so easy to do on your own for free.
Works kinda like selling toast, It works if your a restaurant, but most people would rather make there own toast at home and save money.
Edit: I can just pop on over to https://www.bitaddress.org and then just photoshop in a little logo.

If you are not willing to spend 5 BTC you can't eat my toast.

Obviously you value your time much less than others.
I'm half tempted to dig up that old script that did the exact same thing You are offering.
Maybe even take the two seconds to make it accept a logo option.
At least look at the community, most of these people are smart enough to work photoshop/gimp batch scripts and to use google.
I'm not saying don't do this, im just saying offering toast covered in gold leaf is better then selling plain toast (that we have to provide the jam for).

Thanks for at least reminding me that i never released the version of http://bitcoin.modernjob.info/print.html I made that prints the public key instead of the private key in plain text.

If you try hard enough, you can build plausible deniability into anything, bitcoin being no exception.

Re: The sidescroling game I am making (to be sold exclusively for bitcoin)

Im naming (at least the alpha) Nuclear Future: Avengeance
As I have most of the plot on paper, and all I've got to worry about is graphics and code, I'm going to start the GLBSE stock for it at 0.25 btc (as there is no product yet), and when I start making builds, the stocks can be exchanged (by asset transfer to me) for a compiled product.
I would be glad to scan in the paper with the plot (and my horribly ugly sketching) in to show everyone if anyone wants me to.
Note: I make no promise, express or implied, of any profit or other made from the GLBSE asset. I will only give you this game before the public release, and I also make no promises about date of release.

Edit:
I'll actually make the asset when I can scrounge together 20BTC, forgot about that fee.

We did have a full 3 weeks to record but my mom thought it was cool to die of cancer 2 weeks ago and I just got back from the US.

I'm sorry to hear that Matthew.

I appreciate that. On another note, I had never had a close family member die before, much less of cancer, and I guess I had the idea that it would be like a movie-- either painless and instant, or Godfather "last words" style. I had no idea that cancer basically makes you go senile right before you die, causing you to freak out for a day saying things you've never said, then go open-eye comatose for another day, finally becoming unresponsive until your breathing stops.

My right brain and left brain were both soaking the thing in. Really weird experience. Everyone I talked to after the fact pretty much said that's how their relative/friend went as well. Makes me horrified of cancer even more so.

We weren't that close or anything so I guess I am handling it much better than my oldest sister who keeps shouting it's 'her fault' and something about being 'too late', but one thing is for sure-- I wouldn't even want my enemies to have to live with the pain and suffering she was going through. I am happy she passed quickly and in her sleep (even if her sleep was drug induced).


The last family member I had die of cancer was my grandmother when I was about 6.
She was dying of lung cancer.
The one bit of solace I get from not being able to be with her during her last days was that she, in vain, repeatedly requested I be let in to see her.
I was really close to her as a child, but now I can hardly remember her.
I feel your pain and hope you get though this as quickly as possible.

Since I am going to be working on it all this week, I thought I would say a few things about how i will go about it.
The price will start at 2BTC and then be determined by a GLBSE share (most likely only during the beta phases).
I will open the GLBSE trading once I actually publicly release something.
During the public alpha and beta phases, copies will be acquired by giving me shares of the glbse item (this is to prevent it from becoming a production product before it is ready for release).
I will most likely only make 500 shares or so.

I see potential assuming things are done nicely(and it's not all in flash Tongue )
Flash?
FLASH!?!

Personally i can't stand high level languages, and flash is about as high as you get.
I'm going to school for hardware design, so naturally I want to be able to poke around in the hardware.
So my choice, so people can actually understand the code without ruffling though assembler, is C/C++.

I am still looking for someone to look after this project for me while i am unable to do so. I Would expect my self to be away from this project until about may due to school issues.
On another note: I am looking for some people that have experience with implementing AES or RSA, that kind of math and bit-mangling scares me and i am afraid i would mess something up and make the decryption of the data as simple as dividing by two and then multiplying by three.

Alright, so me and some of the other folks in my CompSci class decided to band together to make a game.
So here is what we have scrounged together as of yet for the plot/teaser:
Quote
The player awakens to find a world desolate, but not destroyed.
It is at this point that the player recalls the series of event's that lead up to this, starting with that chance conversation.
The player was just taking a stroll, when he happened to overhear a terrorist plot.
Their home town was about to become the target of a nuclear terrorist attack.
Despite their best efforts, the player was unable to stop the detonation.
The resulting events caused a sudden and dramatic change in the world, while there was no real threat to humanity as a whole, the series of events left quite a mark (possibility for inclusion of bitcoins as the currency of the world here)
The player must forge his life anew, and enact his revenge on the people that he destroyed everything he loved.
So tell me what you guys think.
