hashcat Forum - 0.42: Bugs

Pages: 1 2

In this thread I'm going to share bugs that still exist in the current latest release of CPU's hashcat (0.42), their severity level and personal workaround if available. Feel free to join me pissing atom off.

Level: Non-critical.
Starting with the flag --hex-salt, as mentioned here: https://hashcat.net/forum/thread-1796.html it was implemented, but in live action it was more than just implementation:

As far as I know, this fuck-up only happens when --hex-salt meet up with -a3.
Workaround: Don't use it.

Moving on...
Level: Non-critical.
--hex-charset is mentioned in --help since 0.40, but turns out to be an "unknown option":

Code:
hc64 -a3 --hex-charset -1 30 hash ?1

hc64: unknown option -- hex-charset

Workaround: Don't use it.

To be continued...

NOTE: I posted this in the Beta section to keep thing a little private, and also, it's not cool for hashcat's reputation to report bugs right after a release. However, I'm ok with moving it the the right section.

bugs are bugs regardless of when it was released. ill take a look and see wtfs up

what was your command line and the hashes? I cant reproduce this.

Well, let's just consider the "keep things a little private" part.

I assume you're talking about the --hex-salt bug.
Details:

Code:
H:

38b3eff8baf56627478ec76a704e9b52:3130

// "101" md5ed

hc64 -m20 -a3 --hex-salt ..\hash.txt ?d

// hashcat-cli64.exe is used

-a0 is just fine. -a3 is the problema.

k, hex charset is fixed, let me see if i can unfuck the

hashcat adds something completely different than the actual hash to hashcat.pot.

Workaround: If you need them so badly, re-hash your passwords.

Hm, thought I fixed this. So its still in there?

Yes, sir.

Level: Non-critical.
hashcat doesn't remove the hash using --remove parameter if it was only one hash and it was cracked.
Workaround: nul > hashfile.

Level: Complementary only
The following info should be added in .\docs\rules.txt:

Code:
#define RULE_OP_REJECT_LESS             '<'

#define RULE_OP_REJECT_GREATER          '>'

#define RULE_OP_REJECT_CONTAIN          '!'

#define RULE_OP_REJECT_NOT_CONTAIN      '/'

#define RULE_OP_REJECT_EQUAL_FIRST      '('

#define RULE_OP_REJECT_EQUAL_LAST       ')'

#define RULE_OP_REJECT_EQUAL_AT         '='

#define RULE_OP_REJECT_CONTAINS         '%'

#define RULE_OP_REJECT_MEMORY           'Q'

With their explanations and also the other new rules (M, X, 4, 6)

I know all of these are just minor matters, hardcore testing phase hasn't started yet. (I gotta study about ventilation-perfusion mismatch and shit @_@)
