the OP's post is not a summary. because it doesnt show the hoax part
take the link to craigs blog..
http://www.drcraigwright.net/jean-paul-sartre-signing-significance/peel away the crap waffle till you get to:
note the signature that craig wright is using..

this is not a signature of a new message but something that is old.. ill get to that bit later
(skipping a stage)
then on the BBC news video interview with craig
https://www.youtube.com/watch?v=dZNtbAFnr-0 he talks about signing a message using "the first transaction ever done in bitcoin"..(mentioned between 9seconds-15seconds in)
hint why choose this particular one out of all the previous 247 keys?? again ill get to that bit later
so the first bitcoin transaction by (real)Satoshi in 2009(block 248):

(thats it, you done pretty much the only thing that craig done (remember no private key was used with what u just done. nor SHA, nor ECDSA)
this is a 7 year old signature of the 7 year old transaction data encrypted using the private key for: 12cbQLTFMXRnSzktFkuoG3eHoMeFtpTu3S 7 years ago
emphasis: the data is the transaction data that is 7 years old(not a new personal message)!! and publicly available.. its nothing new!!
if he was to sign a message today! the signature, even when signed with the same private key would be completely different
emphasis: signing "my name is bob" would result in a different signature than "My Name Is Bob" even when both messages are signed with the same private key.
so if you see him display:
MEUCIQDBKn1Uly8m0UyzETObUSL4wYdBfd4ejvtoQfVcNCIK4AIgZmMsXNQWHvo6KDd2Tu6euEl13VT C3ihl6XUlhcU+fM4=
he is not signing anything new. he is just literally copying and pasting a 7 year old message(tx) that was signed 7years ago
