-This was a failed attempt to create SHA1 algorithm in C. The algorithm achieved still seems sensitive to small changes in text files. So maybe it can be used in stuff like VCS and build systems.
+SHA1 algorithm in C. A single function that reads a file and outputs it's sha1sum.

-2. nsha1file, a function to get nsha1 of a file.
