Post: Nvidia Error cracking RAR hash

I've been getting an error when trying to crack a RAR hash in cudaHashcat64. Once the crack runs for about 10 minutes, it dumps me out with a "ERROR cuSteamSynchronize () 700" I hit the status r...

So I'm sure I have the right dd command for a boot volume now. However, it turns out this is simply an encrypted physical drive, not a system drive - why you'd do that to a 2 TB external USB is beyon...

I thought skip uses the ibs rather than the bs, and ibs defaults to 512. I could be wrong though.

I already realized the error I made. dd should be: dd if=/dev/sdc of=/path/to/file.tc bs=512 skip=62 count=1 I reversed count and bs, and skip should be number of sectors rather than bytes.

I've recently been asked to give a shot at cracking a TrueCrypt boot volume.  Having never done so before, I just wanted to sanity check what I've done. To extract the binary data needed for the c...

    Thread: 12 character WPA2 password
Post: RE: 12 character WPA2 password

Practically speaking, a 12 character WPA2 key is going to be difficult to crack. The WPA2 hash cracks relatively slowly, at least compared with other hashes. 12 characters presents a pretty large k...

It depends on the hash type and which system I am using to crack (and therefore how much speed I can get), but my default rules files are d3ad0ne and generated2. On my fast server, I'll generate a fe...

If you want documentation, go back through the hardware forum and look at some of the posts from around when the 980s came out. Epixoip and others who managed to get 980s right when they were release...

Well damn, and I thought I was going to be the bad kid on the block with the 8 980s I just got.... Guess I just have to start making the case for an upgrade already on next years budget.
