Comparing Password
In this step we compare the hashed password with the plain-text password .
const bcrypt = require("bcrypt");
const plainPassword = "gfgPassword"; //random text
const saltRounds = 10;
bcrypt.hash(plainPassword, saltRounds, function (err, hashedpassword) {
if (err) {
console.error(err);
return;
}
console.log("hashedpassword: ", hashedpassword);
bcrypt.compare(plainPassword, hashedpassword, function (err, result) {
if (result) console.log("Comparion Result : " + result);
else console.log("error " + err);
});
});
Output:
Compare Password
- Compare function is used to compare the plainPassword with the hashedpassword.It also contains the callback function which is used to handle the error if passwords are different.
