    Thread: bcrypt $2*$, Blowfish (Unix) slow speed
Post: RE: bcrypt $2*$, Blowfish (Unix) slow speed

What value is in the "cost" field of your hash? (the second $-separated field, two digits wide)? Based on the speed you're getting, I'm guessing that it's probably cost 10? If so, that speed is norma...

Post: RE: bcrypt $2*$, Blowfish (Unix) slow speed

(Unless you also post the plaintext, please don't post hashes.) Your performance is quite normal for cost 10 on a 1080.

Do you get any errors or warnings? What final feedback do you get from hashcat?

Please do not post hashes. It is against the forum rules (https://hashcat.net/forum/archive/index.php?announcement-2.html). There's currently no support in hashcat for Argon2. hashcat's own help co...

    Thread: How to disable the output of hacked hashes
Post: RE: How to disable the output of hacked hashes

The --outfile/--outfile-format parameters can suppress the console output this way. (If you don't want the output retains anywhere at all, you can map --outfile to /dev/null).

You can mix and match as needed - part rules, part external. A pure-rules approach will be fastest.

In general, the only way to tell for sure is to crack one. Other tools like MDXfind are good at tackling many different algos at once against a pile of unknown hashes. hashcat and MDXfind have some...

It's not open source, but it's free to use. Note also that I've removed the hashes from your post - posting full hashes with non-known plains is against the forum rules.

Not much to optimize here; you're the person best positioned to guess what your own password was. SLI is irrelevant (and even contraindicated; I'd remove it and let hashcat manage the GPUs directly). ...

No, --force would have no effect on not skipping a given platform. Only -D and -d will do that.

That should be irrelevant. Only how special characters (like "?") are escaped on the OS-native command line (not a hashcat issue) should vary between the platforms.
