Can anyone explain it to me?

I somewhere that i can create a private key by rolling 2xD8 64 times to create a key but wouldn't know how to go from there.

Hi there,

I wrote up some instructions for this on the bitcoinpaperwallet.com generator, which also supports a couple of alt currencies.

1) Load up the generator at

https://bitcoinpaperwallet.com/bitcoinpaperwallet/generate-wallet.html2) You can skip the random mouse intro. Click the "Front" tab.

3) Click 'supply my own key'

4) Click for the help button on rolling dice etc, which includes these instructions:

If you want to roll dice or shuffle a deck of cards to generate a key:

Maybe you don't trust that this software (or computers in general) can generate sufficiently random numbers. In this case, you can supply your own random data points from virtually any source. For example, you can roll a six sided die at least 62 times and enter each roll in sequence, e.g. '15249385...' Or, you can mix up a deck of 52 playing cards (after thoroughly shuffling it at least 10 times) and enter at least the top 31 cards in this format: 5S-10H-AC-... (where 5S = 5 of Spades, 10H = 10 of Hearts, AC = Ace of Clubs, etc.)

Essentially what you're doing is rolling dice or shuffling cards etc. just to generate a random string. Then you feed that string into the SHA256 function of the paper wallet software, and this is what gives you your own hand-rolled private key.
