Cannot turn off dynamic chunking

[BenKettlewell]

I'm trying to get a single-machine going and wanted to turn off dynamic chunking to see if that speeds up cracking. I disabled the option but when watching the logs it is still starting, stopping, and restarting hashcat over and over for each chunk.

I checked the database and found you are just storing a 0 or a 1 in the 'use_dynamic_chunking' column on the 'settings' table. 'chunk_size' also defaults to a 0.

That's fine but I think when you're setting up chunking here the unless @settings.use_dynamic_chunking code will always fail to execute as according to ruby both 0 and 1 are "truthy" (ruby truthfulness).

Later you also set a static fall-back value to 50000 but there isn't any logic to skip it entirely if dynamic chunking is disabled.

I also checked trying to increase the dynamic chunk value and it seems stuck on 50000.

Thanks for the heads up. Ill have some time to check on this after the holidays.

Much appreciated. No rush from my end though. I manually upped the static value to 1000000000 and wow what a difference that makes. Went from 3% in 4 hours to doing the whole keyspace in about 20 minutes.

Okay, I think its resolved in v0.7.5-beta code.
