Integer overflow detected in keyspace of mask
I have a hashed string that goes something like this: 392428176.27.938888368973832043. The length is always constant, and the first value (392428176 in this case) is already known. I have made the following mask for hashcat:


But upon running the hashcat (hashcat -m 0 -a 3 hash.txt mask.hcmask), I am getting this error: Integer overflow detected in keyspace of mask.
As far as I am aware, there are 20^10 possibilities of my mask. What is going wrong?
It's 10^20 possibilities.
Okay let's say you bought a new Nvidia 3090 card as described on And let's say your algorithm is the fastest there, MD5 at 66690.4 MH/s.

It would still take 47 years to run through those possibilities. Your mask is just to big.
Unfortunately, the hydra roulette is designed in such a way that the string to be checked in bytes is too large to fit in memory.
There are rare exceptions when a line looks like this: 111111111.1. (16 digits)
