No crypto program is complete without a challenge, so here is mine :-) I'm afraid there is no prize - you will have to be content with fame. To be a little different, the challenge is to forge a signature for
pegwit v8 public key =e935da16bf6950694fde2ada8a0b8641960f68b15fdccbe947ee2415eed34f20
In other words, you have to produce a file and a signature which verifies ( test.txt and files starting with 'pegwit is wonderful' do not count )
To make it easier, I have used only a 6 character password plus a terminating newline. Moreover the password consists of lower case letters (apart from the newline) and is quite easy for me to remember (hopefully!).
If no solution has been found before June 5th 1998, I will reveal the password used, and issue a new challenge.
The password for the old challenge which expired June 5th 1997 was "2+2=10" plus a terminating newline. There were no correct solutions!
In case anyone wishes to attack double-barreled SHA1 rather than going for the private key, here is the signature for test.txt (using the challenge public key). 85886236645e64b60a181d6718385dad0326503dea10fc8c817e041c6559: 0ec24079ba9bd8a3331e4960e457719aa5311d96377050a0f6bfc9dfad2d
You should be able to verify this with pegwit -v
I will also, on request, sign any file beginning with 'pegwit is wonderful'
