Use hashcat with a dictionary of big words

[hmt]

Hi,

I wanted to use hashcat to brute-force all the words in a dictionary file, and the maximum size of the words are 64 bytes.

I modified the common.h file and change the the following lines and then rebuild the code:

#define PW_MAX              128
#define PW_DICTMAX          127

But it seems that hashcat can recover only the wordlist up to size 31 bytes!
What shall I do further if I want to still use hashcat with bigger word sizes?

P.S. I need to use pure sha-1 mode (-m 100)
P.S.S. I use dictionary attack (-a 0)
