Works really well and is fast Posted on Wednesday, February 11, 2004

I used fast_long_roll in an MD5 function and it works a treat. A significant speed increase.

Very useful, genuinely fast Posted by: Colin Chambers on Wednesday, March 31, 2004

Author sent 32 roll function to me some time ago as part of optimisations for MD5. This made a significant difference to the run time for the hashing algorithm.
