Argon2 Password Hashing Parameter Security

Asked 2021-May-26 at 12:20

I'm developing a mobile application and in my lay research of the argon2 password hashing algorithm, it seems that (ignoring the key and salt) there are three main parameters:

iterations
memory
parallelism

While it obviously wouldn't make sense to broadcast these, as far as I see it these will unavoidably need to be compiled within the mobile application and a bad actor could figure out these parameters by decompiling the mobile application.

How protective do I need to be of these parameters?

If these parameters need to be protected, how can I obfuscate these parameters or mitigate the threat to a compiled application? Or, alternatively, can these parameters somehow be distributed by a means other than compiled within the mobile app?

You should not be at all protective of your default Argon2 parameters.

Instead, you should be proud of them.

You should choose parameters that maximize resistance to offline brute-force attack if the hashes are leaked. You should be confident enough in the math behind selecting them to post them publicly, as per Kerckhoffs' Principle.

You have installed an extremely old version of OSMnx. Your conda list output shows you have version 0.7.3 installed, and that was released 3 or 4 years ago. It's so old that it's incompatible with the modern features of GeoPandas and pyproj, including the modern CRS object that's causing your error. I'm not clear how you did it! My best guess is you installed using one of the old tags on this page, which do point to version 0.7.3.

This should be fixed by removing the old environment and then following the installation instructions here, like:

The rust dependency is bring by pywinpty that needs also MSVC. This package

PyWinpty allows creating and communicating with Windows processes that receive input and print outputs via console input and output pipes. PyWinpty supports both the native ConPTY interface and the previous, fallback winpty library.

Then it is not needed on stack heroku-20 that is Ubuntu.

Removing pywinpty from requirements.txt should help.

QUESTION

Can I encrypt password on both frontend and backend?

Asked 2021-Apr-21 at 19:12

I'm making an application that needs logging in.

I used node.js as API.

I understand I have to encrypt the password on backend in case the database is stolen. But if for some reason HTTPS failed or some developer on our side had malicious intention he/she could easily steal the raw password if it wasn't encrypted on the frontend as well.

So my question is is there a problem if I use Argon2 on backend and BCrypt on frontend together?

(Also I assumed that Argon2 is faster so if the attacker wants to brute force he has to use the slow one as well on his side instead of my api heavylifting his/hers shannigans)

I know there are some simillar questions, but they ask if i should use one OR the other and the answer is backend and HTTPS.

I WILL use HTTPS and backend encryption. But I ask if it's possible (or a good idea) to use encryption on the frontend as well.

...

ANSWER

Answered 2021-Apr-21 at 19:12

Argon2 and BCrypt are not encryption algorithms. They're password stretchers (formally "PBKDFs" or "Password-based Key Derivation Functions"). It doesn't make sense to use both, however.

The design you're looking for is this:

Apply a password stretcher on the front-end so that the raw password is never sent to the server.
On the backend, apply a fast hash (SHA-256) so that the hashed password is not stored in the database.

The first part protects the user. Their password never leaves their machine. The second part protects your database. Even if it's stolen, there's no way for an attacker to use the hashes stored there to log into your system.

Jupyter Notebook Cannot Connect to Kernel, Likely due to Zipline / AssertionError

Asked 2021-Apr-12 at 04:17

All of my virtual environments work fine, except for one in which the jupyter notebook won't connect for kernel. This environment has Zipline in it, so I expect there is some dependency that is a problem there, even though I installed all packages with Conda.

I've read the question and answers here, and unfortunately downgrading tornado to 5.1.1 didn't work nor do I get ValueErrors. I am, however, getting an AssertionError that appears related to the Class NSProcessInfo.

I'm on an M1 Mac. Log from terminal showing the error below, and my environment file is below that. Can someone help me get this kernel working? Thank you!

Installing module using Anaconda caused issues on my Virtual Environment

Asked 2021-Mar-31 at 19:41

I attempted to update pandas_datareader on my Python 3.5.2 virtual Environment using Anaconda like this:

...

ANSWER

Answered 2021-Mar-31 at 19:41

At the end, I ended up solving this by rolling back the changes I made using conda list --revisions to find out until which previous set up I had to roll back to, then afterwards I ran conda install --revision N (where N is the revision you want to trace back to). Suppose the changes you made are rev 4, you want to undo them, and sit back again under rev 3 (your previously "known and working" environment you had), so you run conda install --revision 3 for that case.

Afterwards I re-installed pandas_datareader with python -m pip install pandas-datareader and everything went good again.

Thanks anyways and I hope if someone else runs into this issue, can find this post valuable.
