No but perhaps you can create at git-coin command?
I added three new options
--difficulty <leading zeroes>
--prefix <leading digits>
--hex-prefix <leading hex digis>
Be warned tho, this makes it excessively hard. It takes a long long time.Wow, that's fast. Do you know if committer's email also goes into calculation of a git hash? If it is, it should be possible to manipulate git hash in a very discrete way through the email address like this: user+<nonce>@example.com
This already exists btw https://github.com/tochev/git-vanity
What about changing the committer timestamp slightly until you find a match like https://github.com/mattbaker/git-vanity-sha? That would make it entirely invisible
