kandi X-RAY | scrypt Summary

scrypt is a Java library. scrypt has no bugs, it has no vulnerabilities, it has build file available, it has a Permissive License and it has high support. You can download it from GitHub, Maven.

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.

            Issue installing cryptography on Raspberry Pi 2B (armv7h Arch Linux ARM) (python 3.9.8)
            Asked 2022-Feb-05 at 19:41

            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:



            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.



            Rails ( Migrating from Authlogic (6.4.1) that was using SCRYPT to Devise (4.8.1)
            Asked 2022-Feb-04 at 20:04

            I was really hoping to allow existing users on our Rails app ( 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:

            However, at some point our app moved from SHA-512 to SCRYPT by doing the following in order to transition users smoothly:

            Per, 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



            How to remotely deploy a secure websocket service on Tomcat10 through Maven
            Asked 2022-Feb-04 at 13:23

            I have burned myself trying to set up a secure WebSocket service using my remote Tomcat10 server but without any success. I keep on getting from Postman "Unexpected server response: 404" after hitting "wss://". I attach the most important settings in case someone could hopefully spot what I am doing wrong.

            I would like to mention that I am deploying with Maven the project from via a Tunnel.

            Unable to use any Anaconda features even though its installed
            Asked 2022-Jan-14 at 18:00

            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

            1. "conda install anaconda-navigator"

              environment variables: conda info could not be constructed. KeyError('pkgs_dirs')

            2. "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\

            3. 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

            Per 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.



            Answered 2021-Aug-27 at 15:32

            You 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.

            I have a problem with pre-commit hook. The first half of the script works, but the second half that checks max size doesn't. Anyone have an idea what the problem is?



            Answered 2021-Dec-11 at 12:36

            You made at least 2 errors, outside of code:

            • Didn't verify output of |wc -c by hand before using in hook (I can't recall format from memory)
            • Didn't RTFM carefully: piping of $SVNLOOK cat is unnecessary overcomplication, while you have subcommand filesize.
