Find the MD5 hash of a string or file without a trip to the Terminal, or with a system service. Also, compare two files or strings or texts, and a File Integrity Check, which compares a known MD5 hash of a file, to the file, to make sure it hasn't been corrupted.
What's new in this version:
Functionally identical to 2.0, except it's a Universal Application now (hopefully, hence the b1).
