e.g. They said:
Important: verify the md5 sum we have computed before using:
From what I understand, this sum represents a "fingerprint" that is computed from the source code file before it's downloaded. Now, I need to run the file that I downloaded to my PC through (for lack of a better word) and MD5 generator to confirm the download was OK. In other words, this generator should spit out the same hex code.
What is the best way to do the above? (Ideally, the software would be free. :) )
