    Default I can't seem to use rainbowtables with my hash.txt

    I made

    ntlm_alpha-num-symbol14#1-7_0_20000x44505489_oxid#000.rt ntlm_alpha-num-symbol14#1-7_0_20000x44505489_oxid#002.rt
    ntlm_alpha-num-symbol14#1-7_0_20000x44505489_oxid#001.rt ntlm_alpha-num-symbol14#1-7_0_20000x44505489_oxid#003.rt

    using winrtgen. Winrtgen has already sorted them.

    So I put them in /pentest/password/rcrack/rt

    I got the hash.txt from a password cracking guide, password8.zip. It's a normal hash.txt. Looks like the one from pwdump.

    Code:
    [trist007@bt:/pentest/password/rcrack]$ cat hash.txt

    [trist007@bt:/pentest/password/rcrack]$
    Then I try

    Code:
    [trist007@bt:/pentest/password/rcrack]$ sudo rcrack /pentest/password/rcrack/rt/*.rt -h hash.txt
    invalid hash: hash.txt
    [trist007@bt:/pentest/password/rcrack]$ sudo rcrack /pentest/password/rcrack/rt/*.rt -l hash.txt

    Why is rcrack saying that my hash.txt is invalid?

    Default

    I fixed it. I just had to edit the hash.txt to ONLY include the ntlm hashes. I must say, rainbowtables FTW!!!
