Using the Assimilation Bridge (Python Plugin) for Rapid Prototyping

[tha_tux]

Please see in the original post:

Note!!! that in order to use this you need a version higher than 7.0.0, for instance the beta binary from https://hashcat.net/beta or by compiling from GitHub master sources.

This will solve the error: This hash-mode plugin cannot crack multiple hashes with the same salt, please select one of the hashes

I was using git commit hash f47c14603631f545ed4e554b0490ce19afe7e3c8 (very recent from this morning) that still produces that error.

Tried to reproduce with f47c14603631f545ed4e554b0490ce19afe7e3c8, but it works perfect. Here's a log:

[tha_tux]

was a user (my) problem, no idea what happened, sorry..

[tha_tux]

One more question: when running the default Python example (from master, not the changed example from this page) in a Python debugger (or as Python file) the salts are not populated. `calc_hash()` is called but context is empty (as it's not run from hashcat).

```
$ echo -n 'hashcat' | python3 Python/generic_hash_mp.py
578062bebe5d6464de429098aea3b21261a2bd366acc8850066032db1c4d3c67
```

Where I'd expect `33522b0fd9812aa68586f66dba7c17a8ce64344137f9c7d8b11f32a6921c22de*9348746780603343` as output.

Not sure how to proceed, writing a Python function that interprets a hashes.txt file doesn't make too much sense.


Furthermore am I correct in thinking https://github.com/hashcat/hashcat/blob/...lain=1#L98 is out of date as I can't find `def calc_hash(ctx, password, salt_id, is_selftest):` anywhere, I expect it should be `def calc_hash(password: bytes, salt: dict) -> str:`

Again sorry, it's described here in the documentation, that there is no salt an you need to provide it yourself:

"Note that you probably want to inline the correct salt value, see the main section in the code. TBD: Add some sample"

Excellent point. Right now the "hashcat emulation" is not sending the salt used in the ST_HASH, and that is the reason why the result looks different. It was created very early when no salt was involved, so it needs an update. Someone mentioned that they are working on fixing this, but so far I have not received anything from them. Feel free to fix this.
