Recovery not even starting

[cube]

So, I just started using oclHashcat and after my first test passed, and worked (just a simple md5 masked attack against password "hello"), the next ones don't even start.

Or rather, it says it started, and immediatelly stops. Here's the output: (yes, I did modify exec timeout in the registry)

edit: The password I'm testing for now is "aaa".

Code:

First of all, according to the forum rules you are not allowed to post hashes see https://hashcat.net/forum/announcement-2.html

Second, the hash that you use corresponds to a password with 4 characters "aaa\n" where \n represents a new line.

The masked/obfuscated hash for "aaa" (without new line) is 47bXXXc74XX89f48XXXXd5XX9cXXX808

oclHashcat doesn't crack passwords of length 4 if you give it a 3 character long mask.

Sorry, didn't think about it(rules), but thank you for the tip, really didn't realize that I added a new line to my hash, propably typical newbie error. Thank you for the fast response.
