hashcat (v7.1.2) 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.

It returns this same error for every hash type. There's a lot of supported hash types, so I truncated the output to save space.
