How to generate hash for password

Use bcrypt package (to install run go get golang.org/x/crypto/bcrypt) for hashin passwords:

package main

import (
  "fmt"
  "golang.org/x/crypto/bcrypt"
)

func main() {
  pwd := "qwerty123"
  hash, _ := bcrypt.GenerateFromPassword([]byte(pwd), 10)
  fmt.Println(string(hash))
}

• package main - default package declaration
• "golang.org/x/crypto/bcrypt" -
• qwerty123 - sample password string to hash
• bcrypt.GenerateFromPassword - returns hash from given password

group: hash

Example:

package main

import (
  "fmt"
  "golang.org/x/crypto/bcrypt"
)

func main() {
  pwd := "qwerty123"
  hash, _ := bcrypt.GenerateFromPassword([]byte(pwd), 10)
  fmt.Println(string(hash))
}
