oclHashcat for AMD v1.30 slow with "mask"

[Pyrex]

Because you lose the amplifier. That's very technical and goes back how oclhashcat partially reverses the MD5. The best workaround is to use it as a salted hash:

oclHashcat32.exe -m 20 -a 3 8fa1c84f6XXXX38ccXXXXf04274a0c52:keys ?a?a?a?a?a?a?a?a

That'a slower as it can not reverse anymore, but should be faster than 10220.0 kH/s

I was doing something like this today with NTLM I specified a few character of the known password and the rest was a mask and that resulted in significantly slower processing.

Is this due to something similar?

Code:

./hc -w 3 -a 3 -m 1000 ntlm.wrk M?s?l?l?l?s?d?d?d?d
