New Online MD5 Hash Database
Gravix writes with a shameless plug for his new site "Sporting over 12 million entries, project GDataOnline is one of the largest non-RainbowTable based MD5 crackers on the internet. The database spans over 7 languages, 35 topics, and contains common mutations to words that include numbers and capitalization. Average crack time for 5 hashes: .04 seconds. No more waiting weeks for your results!" Shameless plug aside, the site still seems worth a closer look.
Apart from the fact that this site is somewhat morally questionable, it doesn't seem to work very well. I inserted a number of hashes for common first names and dictionary words, and none of them returned a hit. If the database doesn't even cover common stuff such as this, what is it really good for? Really, 12 million hashes out of a space of 2^128 is truly miniscule.
