It is probably because "decrypted.toString('utf-8')" is not executing the function but turning it into a string to show in the console... I believe you have to do something like:

let decryptedResult = decrypted.toString('utf-8'); console.log('Decrypted:', decryptedResult.toString('utf-8'));

or but not sure

console.log('Decrypted:', (decrypted).toString('utf-8'));

Changing python script TBA SHA1 to SHA256

Asked 2021-May-20 at 16:25

I was recently hired as a junior dev as my first job for a bigger company which uses NetSuite. An old dev wrote a python script which handles pictures made by designers, that uploads pictures to NetSuite when they are uploaded to a specific folder.

Since the Script uses SHA1 I need to change the TBA to SHA256 because NetSuite does not support SHA1 anymore.

I have a hard time understanding the old dev's code, and find documentation on how to change the TBA from SHA1 to SHA256..

These are snippets from the code.

There is already sha256() function in Haslib file, so you can try to add a new class SignatureMethod_HMAC_SHA256 into the oauth file which can be similar to that SHA1.

Just change parameters of hmac.new() function like this:

Cannot Uninstall two npm Packages

Asked 2021-May-02 at 02:17

I have installed node-gyp in order to install scrypt. While installing the node-gyp package the following two packages were installed along with it:

101@1.6.3

d@1.0.1

I have tried to remove these two packages, realising that I did not need the node-gyp and scrypt packages, but sudo npm uninstall does not remove them. How can I uninstall these packages?

...

ANSWER

Answered 2021-Apr-07 at 02:41

Its Depends on how you have installed those packages.

if it's a local package to the project

use "npm uninstall --save 'package name'" or simply remove the package from package.json of your project. Then Delete node_modules folder and install npm again using "npm install"

if it's a global package use [sudo] npm uninstall -g "package name"

use sudo based on which OS your are using .

Decrypt an encrypted message with AES GCM in Python

PyCryptodome has a good documentation. The GCM example there uses JSON for concatenating/separating nonce, ciphertext, and tag, but the principle is the same and can easily be applied to your code.

Since you are using the implicitly derived nonce, be aware that PyCryptodome applies a 16 bytes nonce. Note, however, that the recommendation for GCM is a 12 bytes nonce (s. here, Note section).

The following decryption example uses a key and ciphertext created with the code you posted for encryption:

What are the dependencies for django-allauth python:3.8.3-alpine Dockerfile

Asked 2021-Apr-20 at 16:11

I have a Dockerfile, docker-compose.yml, requirements.txt defined below for a django project. The Dockerfile uses python:3.8.3-alpine and the docker-compose.yml have a db service that uses postgres:12.0-alpine image. I made sure that the dependencies are defined in the Dockerfile as required. However, it seems to me that django-allauth require extra dependencies. I have tried for days to fix this issue but get an error that says
This package requires Rust >=1.41.0. ERROR: Failed building wheel for cryptography. I haved pasted the whole error for reference sake. Any help will be much appreciated. Thanks in advance.

ANSWER

Answered 2021-Apr-02 at 11:31

django-allauth requires cryptography which now requires Rust to compile. You could try updating your Dockerfile with the newer python release, i.e. FROM python:3.8.8-alpine, which might let it fetch the prebuilt binary for cryptography.

If that doesn't work you need to add the Rust dependencies so it can compile the package.

QUESTION

Can we generate BCrypt / SCrypt / Argon2 hash password using CNG (Windows Cryptography API)?

Asked 2021-Mar-14 at 20:04

Is it possible with the CNG (Windows Cryptography API: Next Generation) to generate BCrypt / SCrypt / Argon2 hash password ?

BCrypt is a computationally difficult algorithm designed to store passwords by way of a one-way hashing function. You input your password to the algorithm and after significant (relative) computation, an output is produced. Bcrypt has been around since the late 90s and has handled significant scrutiny by the information security/cryptography community. It has proven reliable and secure over time.

Scrypt is an update to the same model from which Bcrypt arose. Scrypt is designed so as to rely on high memory requirements as opposed to high requirements on computational power. The realization that lead to this, was that specialized computer chips (FPGA/ASICs/GPUs) could be purchased at scale by an attacker easier than could huge amounts of memory for a traditional computer.

Short Answer

No.

Long Answer

Neither CryptoAPI nor Crypto API Next Generation (CryptNG) support bcrypt, scrypt, or argon2

bcrypt is a customized version of the blowfish encryption algorithm. Blowfish is not supported by CNG. And even if it was, bcrypt uses a version of bcrypt with a custom "expensive" key setup.

scrypt is (nearly) PBKDF2, which is supported by CNG:

Does my algorithm exist in keycloak or do I have to create a custom credential algorithm ?

From the Keycloak Documentation:

Here’s an explanation of each policy type:

HashAlgorithm

Passwords are not stored as clear text. Instead they are hashed using standard hashing algorithms before they are stored or validated. The only built-in and default algorithm available is PBKDF2.

Nevertheless, Keycloak allows you to customized and deploy your own algorithm by taking advantage of Service Provider Interfaces.
