Password Verification in Node.js

Last Updated : 14 Oct, 2021

In Node for password hashing and verification we can use a npm library known as bcryptjs npm-bcryptjs.

Installation of bcryptjs: Node.js contains an inbuilt crypto module’s randomBytes interface which is used to obtain the secure random numbers.

npm install bcryptjs

Approach:

To hash a password use bcrypt.hash(plainTextPassword, salt, callback) which returns a promise if no callback is passed.
To verify plain text password with hashed password use bcrypt.compare(plainTextPassword, hashedPassword, callback) which also returns a promise if no callback is passed.

Example 1:

// Use bcryptjs module 
const bcrypt = require("bcryptjs"); 
  
// Store the password into variable 
const password = "password123"; 
  
// Use bcrypt.hash() function to hash the password 
bcrypt.hash(password, 8, (err, hashedPassword) => { 
    if (err) { 
        return err; 
    } 
      
    // Display the hashed password 
    console.log(hashedPassword); 
      
    // Use bcrypt.compare() function to compare 
    // the password with hashed password 
    bcrypt.compare(password, hashedPassword, (err, isMatch) => { 
        if( err ) { 
            return err; 
        } 
          
        // If password matches then display true 
        console.log(isMatch); 
    }); 
}); 

Output:

$2a$08$PV4rYpBwXUPAGuMedxUnAOxq/TozK9o/QSUWaKE1XL8psOyZ.JL4q
true

Example 2:

// Use bcryptjs module 
const bcrypt = require("bcryptjs"); 
  
// Store the password into variable 
const password = "password123"; 
  
// Use bcrypt.hash() function to hash the password 
bcrypt.hash(password, 8).then(hashedPassword => { 
   
    // Display the hashed password 
    console.log(hashedPassword); 
      
    // Compare the password with hashed password 
    // and return its value  
    return bcrypt.compare(password, hashedPassword); 
   
}).then(isMatch => { 
   
    // If password matches then display true 
    console.log(isMatch); 
}).catch(err => { 
  
    // Display error log 
    console.log(err); 
}); 

Output:

$2a$08$LKZU9S9WVs3C.S/zpu2U7eua/ocfzD1ytF68QPT5M600auT6M.SxG
true
