Because of probablistic nature of brute force key generation, and

varience of hardware it's going to run on, it's hard to make promisses

about how long it's going to take, especially when the most of users

want just a few keys.\

The probabilty can be calculated with this equation:\
|
||||
$T={32^N \over H}$\
|
||||
where:\
|
||||
*T* is the average time to a match.\
|
||||
*N* is the length of the filter.\
|
||||
*H* is the number of calculations per second.

See [this issue][#27] for very valuable discussion about this.\
