Just to nit-pick this slightly.. This is only true for a perfect hash method, which of course can't exist.. but most hashes are good enough for this to be true. The probability of 2 same length data collisions for something good like MD5 or SHA1/2 is VERY low, so low it's only worth mentioning for nit-picking forum posts, and not practical application. ;-) -- SuperQ ------------------------------------------------------------------------ SuperQ's Profile: http://forums.slimdevices.com/member.php?userid=2139 View this thread: http://forums.slimdevices.com/showthread.php?t=42435 _______________________________________________ audiophiles mailing list [email protected] http://lists.slimdevices.com/lists/listinfo/audiophiles
