MD

MD provides message digests for files in six common algorithms: MD2, MD5, MDC2, RIPEMD-160, SHA, and SHA-1. With all six algorithms at work the risk of collision is again comfortably minimal.Researchers have broken some of the lesser algorithms and are growing suspicious even the longer 160-bit algorithms may not be collision-free.

The US NSA is looking for another killer algorithm. But with MD you should be all right.MD constructs all six message digests at once with the results directly exportable in plain text to disk - meaning you don't run a message digest on a file to prove its integrity, you compare its MD files instead.With all six algorithms working on your behalf the collision risk is more remote than ever.
