    Thread: b64(b64(md5($pass))) supperted by hashcat

With that algorithm you can simply reverse the b64 and then crack the md5

Yes, this GPU has very bad performance when it comes to crypto

Post: RE: Reduced performance

Nope, there's no good AWS GPU. AWS GPU's are good for floating point operations (flops), not raw integer power. In crypto, we need raw integer power.

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: Use hashcat with a dictionary of big words

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.

I didn't miss that, it's a typical OpenCL runtime on OSX fail and some of them are being workaround with hashat v3.20. It was just natural to check with workarounds first. Now that the problem persist...
