help with dictionary required

[Jackjames]

For the first 6 characters you can make a charset with the letters in Capitols and normal.


Last 10 you use the part of the password you know.



The middle you can try and use ?l that should narrow it down a lot?

That's what I am already trying.
The thing is:

even if I am using the first 6 charaters and the last 10 characters fixed, it requires too much time with my current hardware - and with an up to date RTX 3090 it would still have an estimation about 1year...
So... we need to run this for 64 options of the first 6 characters... and in the worst case - on three wallet files.

so it would still be an estimated run time from 3*64 years in the worst case

And I am not yet in the situation that I would consider of buying a 2.000 € GPU for trying this... or spent even more money for building up an SLI etc.

We need to find a way how to ensure and limit the options for the first 6 characters - and then we need to figure out how we can even reduce the amount of possible combinations for the 10 characters of the mid-section.
At least, we have some idea for 6 of those characters, but don't know their exact place and what upper / lower cases are being used on them...

I NEED to find a more efficient way on how to continue. :-(

Im using 5x 3090's and im getting around 360 kH/s

The only way to find another or faster way is to know more about the password or try using combo's i think.
