Hello lindros,

We were both making the same error. There are some hidden control characters in your hex salt. That's causing extra characters to be in the salt. I can verify that there does seem to be an issue on 0.08 with using hex salt with that hash. However as a work-around you should be able to enclose the hash:salt in single quotes, which worked fine for me on 0.08.

Try copy/paste this:
'4a80a448a4a5c5d20024cba8a3c779dd:?$x&XL5w>\c*7,F03G=v~0`THUP{,b'

I can not test on Linux, I do not have
but as you can see it does not work in Windows 7 x64
if I did something bad, it would not work on all versions, but on oclHashcat-plus 0.07 all ok

How are you opening a shell in Windows? There appears to be special hidden characters around the '&' in input & output you cut & pasted. Perhaps there is some strange shell expansion?

The --hex-salt issue with oclHashcat-lite happens in certain circumstances with 0.08. I'm not familiar with the details. It is fixed in 0.09, at least for this use case.

***atom*** · 02-01-2012, 09:41 PM

Yes, its already fixed in 0.09. Thanks for reporting!
