Post: RE: "bug!!" in output / ocl v1.36

It's not Windows-specific, and it's not AMD-specific. I've seen it on Nvidia + Linux. But it doesn't trigger all the time, and it seems to be difficult to reproduce.

Post: RE: CudaHashcat 1.37 0H/s with Bcrypt

Looks like you've tested 2 candidates in 17 seconds, so your speed is ~ 0.11 H/s. This is totally expected. 1. bcrypt is very slow, and depending on the cost value (uknown from above output), it...

There is a reason we tell people to use bcrypt. And, well, you're looking at that reason.

While the 290X is capable of running up to 95C, it shouldn't be getting anywhere near that hot. Especially if the other three cards are water cooled, that 290X really shouldn't be getting any hotter t...

yashar26: You're going to start a fire with that configuration. Why are you coupling a $1000 GPU with a $100 PSU? The 295X2 pulls upwards of 550-575W under compute workloads (though Powertune will do ...

Ok, so in this case your 850W PSU *can't* push 850W, because this isn't actually an 850W PSU. The manufacturer is lying, basically. Your PSU has a single 12V 70A rail which is only 840W, and you shou...

Assuming the plaintext provided is a valid password for one of the two hashes, it doesn't appear to be any of the modes Hashcat supports. Tried 1410, 1420, 1430, 1440, 1450, and 1460 to no avail.

7zip is a very slow algorithm, so your attacks have to be very targeted. Also your GPU is not very good for hash cracking, so you have to be even smarter about your attacks than those with better-perf...

No, your GPU should be several times faster than your CPU for this.

    Thread: RAR3 benchmark
Post: RE: RAR3 benchmark

-b uses -w 3, and 32 is likely too large of a -n value for your GPU. Workload is too large, so speed just hasn't had a chance to update. You can try manually running with a lower -n value.

Well, you have the hash string "MWw4MjlrM2loajFz:qu0VLHJPa2dNL6+7bRIpcRGcdInpFO6B5OGMgnyEeyM=", we assume the first part is the salt and the second part is the hash. Just convert it from base64 encodi...

You cannot achieve any acceleration with a straight wordlist attack against a fast hash on GPU. You need an amplifier to gain acceleration. This is why your brute force speeds are so much faster.
