This command line tool was designed as near drop-in replacements for other sha1sum
implementations. It 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.
