# Password Generator
A simple Golang program to generate random passwords.
## Description
This program generates a random password with a specified length and a combination of lowercase letters, uppercase letters, digits, and special characters. It uses cryptographic random number generation to ensure the password's randomness.
## Features
- Generate random passwords
- Include lowercase letters, uppercase letters, digits, and special characters
- Cryptographically secure random number generation
## Usage
1. Clone the repository:
```sh
git clone https://github.com/saro0307/password-generator
```
2. Navigate to the project directory:
```sh
cd password-generator
```
3. Run the program:
```sh
go run passwordgen.go
```
4. The generated password will be printed into the console.
## Customization
You can customize the program by editing the `passwordgen.go` file:
- Change the length of the password by modifying the `passwordLength` variable.
- Modify the character sets (`lowercase`, `uppercase`, `digits`, `special`) to include or exclude specific characters.
## Example
```go
package main
import (
"crypto/rand"
"fmt"
"math/big"
)
func main() {
// Define the length of the password
passwordLength := 12
// Define character sets
lowercase := "abcdefghijklmnopqrstuvwxyz"
uppercase := "ABCDEFGHIJKLMNOPQRSTUVWXYZ"
digits := "0123456789"
special := "!@#$%^&*()-_+=<>?"
// Combine all character sets
allCharacters := lowercase + uppercase + digits + special
// Generate password
password := generatePassword(passwordLength, allCharacters)
// Print the generated password
fmt.Println("Generated Password:", password)
}
func generatePassword(length int, characters string) string {
password := make([]byte, length)
charSetLength := big.NewInt(int64(len(characters)))
for i := range password {
// Generate a random index
randomIndex, err := rand.Int(rand.Reader, charSetLength)
if err != nil {
fmt.Println("Error generating random index:", err)
return ""
}
// Select the character from the character set
password[i] = characters[randomIndex.Int64()]
}
return string(password)
}
```
