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