Thread: Hashcat 1.20 on Ubuntu 14.04 LTS
Post: RE: Hashcat 1.20 on Ubuntu 14.04 LTS

you can't really claim that you followed that guide since the guide tells you to use ubuntu 12.04 lts, not ubuntu 14.04 lts. 14.04 was just released less than two weeks ago, and is not officially s...

Post: RE: challenge

hashcat does not currently have vanilla pbkdf2 support. you can request it be added on trac if it is important to you.

... yeah, he is trying to fix it. that's why he's asking you to do more extensive testing to try to pinpoint where the problem occurs, and where it doesn't.

Thread: Increasing MD5 GPU Utilization?
Post: RE: Increasing MD5 GPU Utilization?

kind of hard to explain, as this is one of those deep oclHashcat internals topics. but basically the mask is split into a left side (modifier) and a right side (base). the modifier loop is what runs o...

Thread: 2 out of 4 cards detected
Post: RE: 2 out of 4 cards detected

'aticonfig --lsa' doesn't actually show you which adapters are configured for use, it just scrapes sysfs to find pci devices with a matching vendor id. if you recently added the R9 200 cards, you n...

Thread: Increasing MD5 GPU Utilization?
Post: RE: Increasing MD5 GPU Utilization?

your right keyspace is much larger than your left keyspace. try generating a wordlist out of 199?d and then cracking it with -a 6 as -m 0.

Thread: oclHashCat vs WPA @ 9700 H/s
Post: RE: oclHashCat vs WPA @ 9700 H/s

the GTX 650 should be only slightly faster than the 250 GTS. it certainly wouldn't smoke it, they're both low-mid range cards with very similar processing power. it also doesn't help that they're both...

RAID will not protect you from power failures unless you are using a hardware RAID controller with battery- or flash- backed cache.

not just perf per dollar, but nvidia has yet to even match amd's performance. with your budget i'd recommend going with a used gpu. you can use this table to get an idea of how each card performs h...

Thread: MS Cache v2 Cracking Issue
Post: RE: MS Cache v2 Cracking Issue

nothing wrong with your format, it's just a slow algorithm and you presumably have a lot of salts, so it's taking a very long time to check for empty hashes. just add "--weak-hash-threshold 0" to disa...

Thread: How is keyspace calculated
Post: RE: How is keyspace calculated

for -a 3, --keyspace is not the full keyspace of the attack as you might expect, but rather the keyspace of the base loop excluding the modifier. it's pretty complicated, that's why atom recommends y...

Thread: WARNING: Hashfile ..... Weak Hash ???
Post: RE: WARNING: Hashfile ..... Weak Hash ???

'weak hash' means that hash has no input. in other words, it is the hash of nothing/null. in other other words, that account has no password.
