Show HN: I made a C program to create a vanity SHA-1 hash for a text file

Don't bother applying here if your github doesn't look like this:

  $ git log --oneline
  deadbeef5 (HEAD -> master): Revised documentation of frobozz widget.
  0cafef00d scrot_compress: fixed rare recursion case.
  5ca1ab1e1 image_convolve: use thread pool for better performance.

I don't get the last one?
