Revolutionizing Password Strength Evaluation with OpenAI: A New Open Source Project — PSC

Have you ever been tasked with reviewing the strength of password and felt lost in the sea of open-source tools on GitHub? I recently faced a similar challenge when my manager assigned me the job of assessing password strength. Navigating through various GitHub repositories, I discovered that most existing tools rely heavily on code and offer limited features for evaluating password robustness. Moreover, building and maintaining a huge password library seemed like an overwhelming task.

I thought, why not use OpenAI to simplify things? I tested it with a basic prompt:

Check if the password 'Pass!234' is strong, or weak. Please only answer 'strong', 'weak'

In less than a second, I got the answer — weak. That’s when I realized I didn’t need to start from scratch.

Inspired by this, I delved into the OpenAI API documentation (https://platform.openai.com/docs/api-reference/chat/create) and quickly put the idea together with the golang codes.

package main

import (
 "bytes"
 "encoding/json"
 "flag"
 "fmt"
 "log"
 "net/http"
 "os"

 "github.com/joho/godotenv"
)

// checkPasswordStrength sends a request to OpenAI API to check the strength of a password
func checkPasswordStrength(apiKey, password string) (string, error) {
 apiEndpoint := "https://api.openai.com/v1/chat/completions"

 // Prepare the OpenAI API request payload
 input := fmt.Sprintf("Check if the password '%s' is strong, or weak. Please only answer 'strong', 'weak'", password)
 payload := map[string]interface{}{
  "messages": []map[string]interface{}{
   {"role": "system", "content": "You are a helpful assistant."},
   {"role": "user", "content": input},
  },
  "model":      "gpt-3.5-turbo",
  "max_tokens": 50,
 }

 payloadBytes, err := json.Marshal(payload)
 if err != nil {
  return "", err
 }

 // Make the OpenAI API request
 req, err := http.NewRequest("POST", apiEndpoint, bytes.NewBuffer(payloadBytes))
 if err != nil {
  return "", err
 }

 req.Header.Set("Content-Type", "application/json")
 req.Header.Set("Authorization", "Bearer "+apiKey)
