Uh... the relation is like so:

Code:

md2    3.43mb/sec
md4  200.00mb/sec
md5  180.00mb/sec

(Ratio-type estimation, don't remember exact figures this morning.) But it is that drastic a difference.

I don't have MD3 in my system so I can't test it. However none of the md* series is secure anymore. If your hacker knows what they're doing, and they get ahold of your passwords they can do a collision generation in a second or two.

I don't precisely know why MD2 is so slow, perhaps age, implementation, and (lack of) optimization.
