Hashcat vs Keepass 2 (.kdbx)

[Toma]

Hi. Please check if the mask is correctly formed. Translated by Google.

Condition:
Search for the unknown part of the password using the sets: l, u, d. From 1 to 16 characters long (in addition to the known part).

Code:

hashcat64.exe -a 3 -m 13400 -i —increment-min=1 —increment-max=16 -1 ?l?u?d Keepass2.hash Sdkdjso38sLfj9ar?1

And, could you please calculate how long the search with this condition will take. Thanks!!!

hashcat (v5.1.0) starting in benchmark mode...

Benchmarking uses hand-optimized kernel code by default.
You can use it in your cracking session by setting the -O option.
Note: Using optimized kernel code limits the maximum supported password length.
To disable the optimized kernel code in benchmark mode, use the -w option.

* Device #1: Intel's OpenCL runtime (GPU only) is currently broken.
We are waiting for updated OpenCL drivers from Intel.
You can use —force to override, but do not report related errors.
* Device #4: Not a native Intel OpenCL runtime. Expect massive speed loss.
