/* This is the number of bytes of the md5 to actually store in
* the .pag file. This number directly effects the collision
* rate and memory usage. You can probably set this number as
* low as 5 w/o problems and some sites may want to set it as
* high as 8. Anything higher than that is probably not useful.
* Note at the internal hash size isn't the only factor that
* effects collision rate. The table index is used as an implicit
* part of the hash value stored also.
