And the signature:
HM7vpPSUbNsfDHRX6gv8xxWcVNHEc/3pOk0YrVehaGoUdbWizznfzOdELkLd1EjSXsW1oE5vHAkNAPzrAVzhuoI=
how do we know that the two are connected? (I'm guessing one of them hashes to the other.)
I'm honestly not sure there could be a more unreliable source for this
Hal Finney passed away in 2014. But the address has been active since: https://www.blockchain.com/btc/address/1Q2TWHE3GMdB6BZKafqwx... I see four possibilities: * An absurdly elaborate conspiracy. (This is always a possibility.) * Ghosts can do cryptography. * ECDSA is cracked. * Someone else has a copy Finney's key. Occam's razor: spectral signatures!
1) Is there a place on a blockchain explorer somewhere where I could find the signature that Shkreli has posted? I tried looking up the wallet address and found the transaction from Jan 2009, but I don't see that signature anywhere.
2) The reason I ask the first question is that I believe that if the private key is compromised, then whoever has it could have generated a new signature corresponding to that wallet address and any arbitrary message, correct? So if Shkreli is in possession of the private key, he could just be banking on people not actually verifying that the signature he posted appears on the blockchain?

I'll be more sober about it. A cryptographic hash is not proof that data was signed by a particular individual, unless you know for certain that individual is the only person who has the key. That is a hard standard to meet with a dead man when the key has demonstrably been used after his death. That transaction in 2017 means that someone besides Finney simply must know Finney's key. Anything signed by this key cannot be trusted to have come from Finney.
Can someone independently verify the decryption claim here? Should I interpret this to mean that either bitcoin signatures can be attacked via hash collisions, or that they're not actually cryptographically secure, given enough time and computing resources? Either seems bad.
You can verify yourself here: https://reinproject.org/bitcoin-signature-tool/ Use the Bitcoin-QT tab, and don't include the "---- BEGIN" and "---- END" comment lines. It checks out.
I used the Bitcoin-QT tab and filled out the three fields and got a green message at the top of the page that said "Message verified to be from 1Q2TWHE3GMdB6BZKafqwxXtWAWgFt5Jvm3"
