MD5 Sums
Friday 8th September, 2006 10:12 Comments: 0
A friend asked me to do generate an MD5 sum for a large file he was copying off me over FTP (not always the most reliable ways of copying files), and I realised I didn't have any software to do that, as Windows doesn't come with one by default (AFAIK). After a quick search on Google, I came across two useful apps, one is a nice fancy GUI thing to play with, the other one is a neat simple command line application. Both, more importantly, generated exactly the same MD5 sum. They're freeware and they both worked fine with a ~500MB file, so check them out if you need a Windows tool:

MD5Sums
Chaos MD5

I haven't tested these, but I also came across MD5summer and winMd5Sum (the last one looks like it might be a better tool than the other GUIs) and another command line one called md5 that seems to be pushed by a few reputable sites.

If you want to do more than MD5, this command line tool looks pretty good too: FSUM. It handles MD2, MD4, MD2, SHA-1, SHA-2 (256, 384, 512), RIPEMD-160, PANAMA, TIGER, ADLER32, CRC32 (as well as a custom hash algorithm used in eDonkey and eMule applications) and has been tested on files up to 15GB.
