No - what Craig did was grab an existing signature used by Satoshi and pretend he had created it to sign a document by Sartre (which is fraud and even Gavin is not sure what on earth to make of that).
And he *is* claiming to be Satoshi (which is why he asked Gavin to come and *verify* his claim).
Also - why are you posting the exact same thing in multiple topics?
Re-read my post, you didn't seem to understand it. Craig has not said he is Satoshi. Find a quote where he said that. You won't. He has always said it was his colleague.
And with his access to a supercomputer, it is plausible he was able to reverse the hash in order to find a text that matched the signature that was already on the blockchain. Without that explanation, then he must have the private key! You seem to not understand the technology.

I am replying to every topic where my post is relevant. I am not the one who created so many duplicate topics.
