I received a refund of the agreed upon amount. I never thought this would actually happen. Huge thumbs up to the owners.

You must be a shill to judge BFL shipped here. +1 to the scammer tag, but I doubt it will happen.

Congrats, I was nearly done but had some annoying bug left. I'll check performance in firefox and see if my code happens to do better though. (Unlikely though if your scrypt is also based on this one: https://github.com/cheongwy/node-scrypt-js)

I finally have a scrypt implementation in pure javascript that passes all test vectors at http://www.ietf.org/id/draft-josefsson-scrypt-kdf-01.txt. I won't release it now because I plan to go for the bounty. If I somehow abandon that I will put it up on github.

Curious, have you got even the last case with N=1048576?  Mine is crashing the Chrome tab it lives in, and even nodejs (message about running out of memory).  (With the smaller N-values BIP38 needs it works though.)

Crashes for me too. I think I could possibly get it to work but I'm not going to bother since the BIP38 stuff works.

How far along are you on the whole thing?

Can someone provide the ownersalt used for these test vectors? It appears to be missing or I'm misunderstanding something. I need to test the process until the intermediate code.

EC multiply, no compression
Test 1:

Passphrase code: passphrasepxFy57B9v8HtUsszJYKReoNDV6VHjUSGt8EVJmux9n1J3Ltf1gRxyDGXqnf9qm

Test vectors

No compression, no EC multiply
Test 1:
Passphrase: TestingOneTwoThree
Encrypted: 6PRVWUbkzzsbcVac2qwfssoUJAN1Xhrg6bNk8J7Nzm5H7kxEbn2Nh2ZoGg
Unencrypted (WIF): 5KN7MzqK5wt2TP1fQCYyHBtDrXdJuXbUzm4A9rKAteGu3Qi5CVR
Unencrypted (hex): CBF4B9F70470856BB4F40F80B87EDB90865997FFEE6DF315AB166D713AF433A5


Result by decryptbip38.js:

Encrypted key: 6PRVWUbkzzsbcVac2qwfssoUJAN1Xhrg6bNk8J7Nzm5H7kxEbn2Nh2ZoGg
Passphrase: TestingOneTwoThree
Private key: cbf4b9f70470856bb4f40f80b87edb90865997ffee6df315ab166d713af433a5


Now for the EC version. Shouldn't be much harder.

here maybe, but it looks like it needs some work: https://github.com/cheongwy/node-scrypt-js

That one only works for node and uses a lot of external modules. I'm trying to follow the coding style and let it work in the browser but it doesn't look too hopeful with my coding skills.

the bounty can be collected in full with just the ability to decrypt any variant of BIP38-encrypted private key.

Quote
The winning solution needs to properly handle the compressed private key flag, as well as the variants of encryption that include and exclude the elliptic curve multiplication step as well as the flag that turns on the presence of a sequence number.

The second section seems to imply you meant every instead of any right?

  A 10kW electric furnace produces the same amount of heat equivalent to 10 kW of GPUs. 


This is not really true, as some of the energy get's converted into noise. For all intents and purposes this is correct though Wink.

I will buy old gpu's, and use them to heat my house =D
It's cold and rainy where I live, and heating is useful everywhere!
I figure 10 kwh through video cards is better returns than 10 kwh through heaters =/

Ah, yes and no. Smiley  Heaters will probably give you more efficient conversion of power to heat compared to the cards, but it might be close. Smiley

For converting electrical energy to heat, almost any device is effective because it's basically the "waste" that's heat. Gas -> heat is still more cost-effective though.

3600, let's see that's about 18 times the original investment. It might be high risk, but a 2000% return is just too good to pass up.

So whether the government is robbing you depends on whether they have a legal claim on the money they are taking. Simply taking it by force is not enough.

I don't expect you to agree with me now, but is it any clearer where I am coming from?

From a personal perspective, the more of that expropriated property that is misappropriated by government for all kinds of corrupt and inappropriate purposes, the closer I am drawn to pure-anarchist thinking. Years ago, I would never have imagined considering anarchy potentially a good thing.

If I could somehow allocate my taxes to certain areas and exclude others (army, corn and other farming subsidies) I would feel better about paying them.
