Mask Attack -> Approaching Final Keyspace - Celare - 07-20-2016
Hi,
Kinda new to this and I'm having an issue with getting Hashcat to work.
Upon running Hashcat, it gives me "INFO: approaching final keyspace, workload adjusted" and stops.
This includes all example.cmd's included with the binaries.
Rig has SLI GeForce GTX 980s and updating the drivers seems to do nothing.
Any pointers?

... What exactly is the issue here?
RE: Mask Attack -> Approaching Final Keyspace - Celare - 07-20-2016
It's not cracking hashes and stops 4 seconds after execution. This is true even for a 12 character password.
Heres what I'm running
hashcat64.exe -m 1400 c4b4f1914f1c7cd67ff77939309716518d7b08e4e5323c148f4924229c9e1041 -a 3 -1 123456789 -2 !d!u!l '?1-?2?2?2?2?2?2?2?2?2?2?2?2'
pause

SLI does not matter for hashcat, could just be simply avoided.
"It's not cracking hashes" doesn't mean much, unless you're 100% sure it should crack them, if that is correct either hashcat has a bug, or, as most of the time it comes from the user.
And in your case, I'd say you should read this : https://hashcat.net/wiki/doku.php?id=mask_attack#masks

Not sure what you think the passphrase scheme is but it looks like you're aiming for this mask?
Code:
-1 1234567890 -2 ?d?u?l ?1-?2?2?2?2?2?2?2?2?2?2?2?2A digit, a dash, then 12 chars (digit/upper/lower).
Should only take about 627 millennia to get through the keyspace.
But wait! You have TWO cards!...

This is pebkac!
Such a keyspace is done in no time: 10 * (4 ^ 12) = 167,772,160

I've gotten it to work with a basic password (abcdef) however adding a hyphen to any mask that I try breaks it.
4-abcdef SHA256-> 64290b5930c1cf9e269d639cfdd51a7cf26c01b540e35502f09c30802dd8745e

Doesn't work.

Working ok for me...

Celare still struggling with the difference between ! and ?
RE: Mask Attack -> Approaching Final Keyspace - atom - 07-24-2016
Yes, I already said it's pebkac.
