MD5

Implementation of the MD5 algorithm written in C

Original Source: https://github.com/pod32g/MD5/tree/5b2587f1330f1010b85c3a8c277e70936061ce4a

Modification: The original code runs the MD5 algorithm 1M times for benchmarking purposes. I modified that portion so it only runs once. Also, I added support for reading input from stdin (along with from CLI arguments).
