longDescription = ''
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.
