The way to Create a Password Generator in Golang


In as we speak’s digital age, password safety is extra vital than ever earlier than. Hackers can simply guess weak passwords, resulting in id theft and different cybersecurity breaches. To make sure our on-line security, we have to use sturdy and safe passwords which are troublesome to guess. A superb password generator may help us create random and powerful passwords. On this weblog put up, we’ll focus on tips on how to create a password generator in Golang.


To create a password generator in Golang, we’ll want the next:

  • Golang put in on our system
  • A textual content editor or IDE

Producing a Random Password in Golang#

To generate a random password in Golang, we’ll use the “crypto/rand” package deal.This package deal gives a cryptographically safe random quantity generator. The next code generates a random password of size 12:

package deal primary

import (

func primary() {
	const charset = "abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789"
	const size = 12
	b := make([]byte, size)
	for i := vary b {
		n, err := rand.Int(rand.Reader, massive.NewInt(int64(len(charset))))
		if err != nil {
		b[i] = charset[n.Int64()]
	password := string(b)

On this code, we outline a continuing “charset” that incorporates all of the doable characters that can be utilized within the password. We additionally outline a continuing “size” that specifies the size of the password we wish to generate.

We then create a byte slice “b” of size “size”. We use a for loop to fill the byte slice with random characters from the “charset”. To generate a random index for the “charset”, we use the “crypto/rand” package deal to generate a random quantity between 0 and the size of the “charset”. We convert this quantity to an ASCII character and add it to the byte slice.

Lastly, we convert the byte slice to a string and print it to the console.
