Password cracking

Hey Guys,
Are there some openly available lists of hashed passwords to play around
with? I know, surely Google knows some of those, but it seems I'm to
stupid to find them.

My second question concerns Rainbow tables. It's quite simple, but I
cannot grasp this reduction function which maps a hashvalue to a
possible password. Are there some agreed-upon standards? What does this
function look like, say, if I wanted to implement it.

Best regards
Yuri
