Limit length of hash?

[toomanyjoes]

Is there a way to limit the length of the hash to a certain number of character?

[miquelfire]

You would need to limit the number(s) used to generate the hash.

If you're only using 1 number to generated the hash, make a loop, and stop it once the number is more than the limit, and you have your max value.

There's no way to set the max length (only min). It's not a hash, but an id. Since they're generated by encoding numbers, sooner or later you'll overflow any length.
