SHA1 Broken? See here.
Here is a nice table of hash functions and attacks.
Sam makes an interesting point. We probably don’t have to worry about this too soon..
"Dougal, put another way: an uncracked MD5 gives you 128 bits of protection. A "broken" SHA-1 gives you 160-11=149 bits of protection. That is still 2,097,152 (2**21) times more secure than MD5.
