Securely Generating Passwords for ShadowSocks

in

And specifically, how to securely generate passwords for ShadowSocks.

Now, if you don’t know what ShadowSocks is, it’s a pretty awesome tool that allows you to encrypt your traffic and bypass censorship restrictions. But in order to use it, you need to have a strong password (because let’s face it, nobody wants their sensitive information falling into the wrong hands).

So how do we go about generating these passwords? Well, there are a few different methods out there, but we’re going to focus on one that’s both secure and easy to use: using Python.

If you don’t already have them installed, go ahead and run the following command in your terminal or command prompt:

# Install the pycryptodome3 library using pip
pip install pycryptodome3

# Generate a random 16-character password using the pycryptodome3 library
# The password will be a combination of uppercase letters, lowercase letters, and numbers
# The password will be stored in the variable "password"
password=$(python -c "from Crypto.Random import get_random_bytes; import base64; print(base64.b64encode(get_random_bytes(12)).decode('utf-8'))")

# Print the generated password to the terminal
echo "Your randomly generated password is: $password"

This will download and install the PyCryptoDome library, which we’ll be using to generate our passwords.

Now that we have everything set up, let’s write some code! Here’s a simple script that generates a random password based on your input:

# Import necessary libraries
import random # Import the random library to generate random characters
from Crypto.Hash import SHA256 # Import the SHA256 hash function from the PyCryptoDome library

# Define main function
def main():
    # Get user input for desired length of password
    length = int(input("Enter the desired length of your password (minimum 8): ")) # Prompt user for input and convert it to an integer
    
    # Check if input is valid
    while length < 8: # Use a while loop to ensure the password length is at least 8 characters
        print("Error: Password must be at least 8 characters long.") # Print error message if input is invalid
        length = int(input("Please enter a new value for the password length: ")) # Prompt user for new input and convert it to an integer
        
    # Generate password using SHA256 hash function and random string of characters
    salt = b"salt" # Define a salt value to add to the password for added security
    hashed_password = SHA256.new((b"my-secret-key" + salt).encode("utf-8")).hexdigest()[:length] # Use the SHA256 hash function to generate a password based on a secret key and the salt value, then truncate it to the desired length
    
    # Print generated password to console
    print(hashed_password) # Print the generated password to the console for the user to see

# Check if the script is being run directly
if __name__ == "__main__":
    main() # Call the main function if the script is being run directly

This script uses the SHA256 hash function (which is a secure and widely-used cryptographic algorithm) to generate a random string of characters. The salt value ensures that each password generated by this script will be unique, which helps prevent attacks like rainbow table or dictionary attacks.

A simple yet effective way to generate strong passwords for ShadowSocks (or any other application that requires secure authentication). And the best part? It’s all done using Python, so you don’t need to be a cryptography expert to use it.
