backslash(\) slow down md5 speed - erikass - 11-11-2018
hello again
firstly salt info:
salt1:\337
salt2:\245\144\076\274\375\145\313\316\251\071\157\227\307\323\251\005
im trying recover salt md5 hash but there is no option in hashcat for that salt, md5(salt1.pass.salt2) and I did just little changes and its working right now BUT that speed its really slow..
and I realized what is the problem.
once I'm using hashtype:10 for md5 salt well this is like md5(pass.salt) and then I created text file for hash its like that
pass: (salt2)
and using attack with that mask (salt1)?d?d?d?d?d?d
BUT its very slow because when I add salt1 I think problem is backslash(\) speed decreased very much
outputs:
without backslash(\):

any suggestion thanks

Static prefixes in a mask attack slow down the attack, that's a known limitation in hashcat. Avoid static prefixes if possible and try to change your attack.

Worked like hell!!!! thank you man
I changed hashtype 10 to 20 md5(salt.pass)
and its worked
edit: not too much different but its ok
