Free and cross-platform Java MD5/SHA sum generator
Version: 0.6JMd5Sum is a free md5sum GUI utility that would work in Linux, OS X and Windows.
Operating System: Mac OS X
JMd5Sum is an easy to use cross-platform Java MD5/SHA sum generator that also does SHA1 sums, as that's becoming the favorite after some recently discovered vulnerabilities with MD5.
JMd5Sum is half as fast as a pure C implementation, so it will do a 100 MB file in a few seconds, not a minute or more like it did before (on relatively modern machines).
