TypeError: Pass phrase must be a buffer

Code:

var custschema= new mongoose.Schema({
    email: { type: String, unique: true, required: true },
    name: { type: String, required: true },
    role: { type: String },
    hash: String,
    salt: String
});

custschema.methods.setPassword = function(password) {
    this.salt = crypto.randomBytes(16).toString('hex');
    //this.hash = crypto.pbkdf2Sync(password, this.salt, 1000, 64, 'sha512').toString('hex');
    var buffer = new Buffer(this.salt, "binary");
    console.log(this.salt);
    console.log(buffer);
    this.hash = crypto.pbkdf2Sync(password, buffer, 1000, 64, 'sha512').toString('hex');
};

custschema.methods.validPassword = function(password) {
    //var hash = crypto.pbkdf2Sync(password, this.salt, 1000, 64, 'sha512').toString('hex');
    var hash = crypto.pbkdf2Sync(password, new Buffer(this.salt,'binary'), 1000, 64, 'sha512').toString('hex');
    return this.hash === hash;
};

Can somebody please guide me or enlighten me whether they have face this issue or not. Let me know if you want any more details.

Thanks

Answer 1

crypto.pbkdf2Sync returns Buffer and you are storing in the string OR you can convert buffer to string and store.

You can change the hast type to the Buffer and try Check mongoose data types here
