kandi X-RAY | scrypt Summary
Java implementation of scrypt. A pure Java implementation of the scrypt key derivation function and a JNI interface to the C implementations, including the SSE2 optimized version. The Java implementation is based in large part on Colin Percival's reference implementation contained in crypto_scrypt-ref.c, but any errors in this port are solely the fault of its author, Will Glozer.

QUESTION
I'm having some trouble installing the python cryptography package on my raspberry pi, specifically with python version 3.9.8 (installed with pyenv). The cryptography package is installed on my system using pacman (python-cryptography package), and thus works using the main python interpreter (3.10.1). However, I need some version of python 3.9 specifically for another package I am using in this project. Any time I try to install cryptography through the python 3.9.8 environment, I get the following error:
ANSWER
Answered 2022-Jan-14 at 19:59@jakub's solution ended up solving the problem for me. I uninstalled the version of rust that was installed through pacman. To replace it, I installed rustup and then using rustup, installed the latest nightly version of rust (1.60). Once I did that, installing the cryptography package worked just fine.
If you are using rustup, just make sure that you add ~/.cargo/bin to your PATH before installation. Also, the command I used to install rust through rustup was rustup toolchain install nightly.

I was really hoping to allow existing users on our Rails app (6.0.4.1) that is currently using Authlogic (6.4.1) to be able to log in using existing passwords when we migrate to Devise (4.8.1).
Every article that I've seen has a nice explanation of how to do it IF the encryption is SHA-512. In those cases you modify config/initializers/devise.rb and setting config.encryptor = :authlogic_sha512 (source: https://gist.github.com/rpheath/8343779).
However, at some point our app moved from SHA-512 to SCRYPT by doing the following in order to transition users smoothly:
...ANSWER
Answered 2022-Feb-04 at 20:04Per https://github.com/heartcombo/devise/issues/3779, use devise-scrypt.
The common solution for this still seems to be using the devise-encryptors and devise-scrypt gems which means a number of additional of moving parts.
Yes, Devise supports other encryptors via extensions, that's the way to go. -José Valim

QUESTION
I have installed Anaconda from its site and was working fine for sometime, however I needed to install Plotly and used the below steps mentioned in another site. I just got it up and running on spyder 3.0 using the following steps. (windows 10)
Download plotly using pip usig command line (python -m pip install plotly) this requires downloading python 3.5 separately from Spyder as well. (so far I haven’t had any conflicts) In Spyder, goto->Tools ->PYTHONPATH Manager -> addPath -> insert path to Plotly library (mine was in python\python36-32\Lib\site-packages), then synchronize Restart Spyder test it out with import plotly.plotly \n import plotly.graph_objs as go in a new .py scrypt Hope it works out for you. Cheers
After the above steps I was able to import plotly in Spyder and didn't face any issues, however after I restarted my machine I'm unable to run Anaconda navigator or Spyder. I'm able to launch Anaconda prompt but any command executed returns different kinds of errors like
"conda install anaconda-navigator"
environment variables: conda info could not be constructed. KeyError('pkgs_dirs')
"spyder"
ImportError: cannot import name 'constants' from partially initialized module 'zmq.backend.cython' (most likely due to a circular import) (C:\Python\Lib\site-packages\zmq\backend\cython_init_.py)
anaconda-navigator
ImportError: DLL load failed while importing shell: The specified module could not be found.
I tried every solution on internet like uninstalling and reinstalling, deleting all the trace files on anaconda and even the Environment variables seem to be fine
echo %PATH% command returns
...ANSWER
Answered 2022-Jan-14 at 15:34Per this github issue, you may have a conflict between dependencies of packages anaconda installed and the one you installed manually. Check your pythonpath and see if removing the pip folder from the pythonpath fixes the issue.

I am starting to write end-to-end testing in nestjs. even the first simple test failed.
...ANSWER
Answered 2021-Aug-27 at 15:32You set up cookieSession in your bootstrap, but your bootstrap has nothing to do with you tests. You need to call the same app.use() in your test setup that you would in your bootstrap to have middleware parity, or move the middleware to a Nest Middleware so you don't have to worry about this in the future.

Install scrypt
You can use scrypt like any standard Java library. Please include the the jar files in your classpath. You can also use any IDE and you can run and debug the scrypt component as you would do with any other Java program. Best practice is to use a build tool that supports dependency management such as Maven or Gradle. For Maven installation, please refer maven.apache.org. For Gradle installation, please refer gradle.org .
