The moment you put something personal into the passphrase, an attack that can crack your passphrase becomes an attack on *your passphrase exclusively*. Unless you have a very well funded brain wallet, the whole cracking enterprise is no longer economical. [EDIT:] using many rounds of hashing plus conditionals after each round pulls the teeth of SIMD & friends to an extend.

But I think a passphrase should not only be long, it should also force the attacker to use a vast dictionary of many Billion entries to even have a chance to crack it. I think most dictionary attacks completely loose their teeth if you mix languages like ລາວ, 中文, ไทย, or even Ελληνικά, particularly if the passphrase contains local slang in these languages.

So if everyone just makes good use of their native language this only leaves those out in the rain who speak only English. Fine.

We can leave them alone. Coordinating a massive spam attack was a bad idea even before they explained their reason to avoid Bitcoin (however little sense it makes).

The Humble bundle will change their mind with time, until then there are other organizations needing our help learning about Bitcoin and starting to accept payments.

En vez de explicar temas de criptografía, yo explicaría cómo se obtiene una bitcoin de un bloque determinado.

Cogería el ejemplo de un bloque "x" y empezaría desde el funcionamiento de una pool que envia shares hasta que se libera el bloque y cómo podemos usar las bitcoins liberadas por ese bloque.
Todo explicado paso por paso con sus respectivas "matemáticas".

This sounds pretty good.  I might use a variant on that at one point.

To address the criticism that using one passphrase means the whole wallet is lost once the passphrase is gained, there's no reason you can't have multiple passphrases.  It seems to me that any deterministic wallet generation scheme is vulnerable if the seed is compromised.

Is there a tool that can be used offline that generates a public key from a sha256?  Preferably in javascript or shell script?

sorry to derail the topic -  Coinabul - I never got my order confirmation over the weekend.  I placed an order for two silver coins.

YAY! Got my coins back!!
Thanks BTC-e!!

Hey, that's false. We stopped accepting BTC-E coupons when the attack started.

As soon as trading starts, we will turn it back on.

Yup,

Most of the tx's were released, just waiting on the confirmations.

Thank you people, you have been more than helpful. I just updated it to the newest version and it's currently synchronizing with the network.

Yes, but HOW... I would either need to shift my whole cart to a new platform, or do everything by hand (and still pay the exchange fees). Both increase costs. taking bit-pay as an example I only save .59% over pay-pal (16 cents on the average transaction.)

Lets say that I could change carts (or hire a developer) for $5,000. Our average sale is around that 27 dollars I used in the example.  It would take 31,250 bit coin sales to JUST BREAK EVEN! That would take years, even if every transaction that we took shifted to bitcoins. If I processed ten bitcoin transactions a day, it would take 8.6 years to break even. And when I was taking bitcoins last year, I had about 2 a week which would take 300 years!

Even if it just cost me $1,000 to implement bit-pays automated solution it would not be worth it.

Lets look at the math doing it by hand with gift cards... Again, on the average transaction using bit-pay I save .16 cents. So someone I pay $10 an hour would have to be able to get the email notifying us of a bitcoin sale, go into our shopping cart software create the gift card (then sell the gift card from our online store into our POS system so that when we ring up the sale of the goods there is a way to pay for it in POS) and then write an email to the person with their gift card number in there... all in under 1 min... and thats just to "break even".

Bit-pay is a more expensive way to do it, I would not use them unless it was automated, if im going to be doing things by hand anyway, i might as well use a cheaper solution... but as the person pointed out before, there is no real good solution... as mtgox is cheap, but can take two weeks to send the money! I will contact bit-pay and see if they have any interest in developing a 3dcart plug-in-play solution.

EDIT: But maybe im just too emotional to see the true value in bit coins

How do I do that? BackupWallet?

...

They will tell paypal you bought virtual goods and you wont be able to chargeback  

when I visit the website from home, it show 403 error.....
And when I go to some other place to go internet, it went well.

And some of my friends confirm that they encounter the 403 error too.

Does someone encountered the same problem? Is the problem related to my home ADSL network (and some of my friends') or the problem related to the bitcoinadvertisers website?
