How to Produce a Password Generator in Golang


In today’s digital age, password security is more vital than ever previously. Hackers can quickly think weak passwords, causing identity theft and other cybersecurity breaches. To guarantee our online security, we require to utilize strong and safe and secure passwords that are hard to think. A great password generator can assist us develop random and strong passwords. In this post, we’ll go over how to develop a password generator in Golang.


To develop a password generator in Golang, we’ll require the following:

  • Golang set up on our system
  • A full-screen editor or IDE

Getting a Random Password in Golang

To produce a random password in Golang, we’ll utilize the “crypto/rand” package.This plan supplies a cryptographically safe and secure random number generator. The following code creates a random password of length 12:

 plan primary

import (
" crypto/rand".
" math/big".

func primary() {
const charset="abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789".
const length = 12.
b:= make([] byte, length).
for i:= variety b {
n, err:= rand.Int( rand.Reader, big.NewInt( int64( len( charset)))).
if err!= nil {
panic( err).
b[i] = charset[n.Int64()]
password:= string( b).
fmt.Println( password).

In this code, we specify a continuous “charset” which contains all the possible characters that can be utilized in the password. We likewise specify a continuous “length” that defines the length of the password we wish to produce.

We then develop a byte piece “b” of length “length”. We utilize a for loop to fill the byte piece with random characters from the “charset”. To produce a random index for the “charset”, we utilize the “crypto/rand” plan to produce a random number in between 0 and the length of the “charset”. We transform this number to an ASCII character and include it to the byte piece.

Lastly, we transform the byte piece to a string and print it to the console.
