      This library and command line tool were designed as near drop-in
      replacements for common SHA-1 libraries and sha1sum. They will
      compute the SHA-1 hash of any given file and additionally will
      detect cryptanalytic collision attacks against SHA-1 present in
      each file. It is very fast and takes less than twice the amount
      of time as regular SHA-1.
