For old AMD cards you need to use windows, otherwise you're lost. New linux drivers need 290x or newer.

Yeah, the clEnqueueReadBuffer () is an error from OpenCL subsystem which comes with driver not hashcat.

Post: RE: am I doing something wrong?

But if hashcat can not find it, it's either an invalid offset or the mask is invalid. To find out which of them is true, I can only see one way. You need to build a bootable veracrypt system and repro...

I had added support for this to hashcat v3.20, but it was bugged in case of WPA. Should be fixed with latest beta on https://hashcat.net/beta/

Post: RE: Use hashcat with a dictionary of big words

Total wrong approach. If your algorithm creates 128 byte intermediate values you need to handle that inside a dedicated kernel for that algorithm.

Post: RE: Combinator attack with a maximum length?

Hashcat can not show an ETA because it can not know the total number of password candidates you're sending in.

You can use --gpu-temp-retain 1 to tell hashcat to set the fans to 100% for you, so you don't need any external tools

Yes, I can reproduce the same behaviour. Mask is fine, but rule-based dropped from ~600MH/s to ~300MH/s. Also the OpenCL JIT compiler segfaults while compiling the scrypt kernel. That errors occur in...

Typical WPA case and it's always because of a bad handshake capture. Just do a new one.

Yes, block size for sha1 is 64, but if the data part is >= 55, then it requires two calls to sha1 transform because of merkle-demgard construct.

That's wanted. It makes sure it has write-permission to the outfile. Imagine you're cracking a hash and hashcat can't write to outfile and errors out.
