Hi,
One question on Ethereum wallet: a user need to send you the whole keystore json right?
There is no lucky feature like in Bitcoin to send you just a bit of the wallet?
Just some curiosity: how many guesses per second can you perform on a single instance?
Thanks for your time.
Hi. That is correct, for both the ethereum presale and ethereum wallet formats, there is no way to send 'limited' information which enables trustless third-party decryption of a wallet.
On my rigs, guesses/second is in the range of 300,000/second for GPU based ethereum pre-sale wallet decryption (but much less for the mist/ethereum wallet format).
Cheers
Dave
