Being statistically random means probability of two strings to collide is the same as probability of two random hashes to collide, IIRC. I.e., 1/2^$LENGTH_OF_THE_HASH. If you interested in *real* analysis, just take Shneier's Applied Cryptography, 2ed, and study :)

Is that true, I´ve never benchmarked and I´m using it frequently... -- o----------0-¬---------O-·---¬----o---®-----o o O ° . | http://www.kiffen.de | pRoteçt y0ur bRaín |0 O ° ¤ ° · 0°·³°²'²³-¹'³´³°^°³~³²³°'³²²¨³²^³¹³²°²³`³º³°Þ ° o © ° . · | psychedelic experience | gott@kiffen.de | O ° o ° o-¬--o--0-----©-·--O-----o-----0-¤----------o 0 ° · ° . ¤ ·
