| Passwords are not a viable method of authentication anymore. |

I have said it before, and will keep on saying it... Passwords are not a good mean of authenticaion. The problem is... it is in most areas the only available mean of loging in. The advent of Rainbow Tables makes it VERY easy to crack a huge number of password in very little time. The way it works is by pre-computing a list of all the hashes corresponding to all the possible encryption for all characters. Once you are in possession of such a table (can be huge), you just need to lookup the password hashes you are looking for and you are all set. I just found the following post, which describes the whole process and ease of use. Once again, Windows is the worst operating system security-wise, due to their legacy use of a non-salted / limited number of characters... Anyways, much more information at: http://www.codinghorror.com/blog/archives/000949.html
