data and salt required : hashSync
hashSync function is a method used for hashing data in Node.js applications using the synchronous version of the bcrypt library. The function takes two arguments: the
data to be hashed and the
salt value to use when generating the hash.
data argument is the data that you want to hash, such as a user’s password. The
salt argument is a random value that is used to increase the security of the hash. The salt should be unique for each user and should be stored alongside the hash so that it can be used to verify the hash in the future.
Here’s an example of how you might use the
hashSync function to hash a user’s password:
const bcrypt = require('bcrypt'); const password = 'password123'; const saltRounds = 10; // Generate a salt const salt = bcrypt.genSaltSync(saltRounds); // Hash the password with the salt const hash = bcrypt.hashSync(password, salt); console.log('Salt:', salt); console.log('Hash:', hash);
In this example, we generate a random salt using the
genSaltSync function and a
saltRounds value of 10. We then use this salt to hash the
password using the
hashSync function. Finally, we log the
hash values to the console.
