We need to create a service called jwToken.
Go to api/services directory and create jwToken.js.
'use strict';
const jwt = require('jsonwebtoken'),
tokenSecret = "secretissecret";
module.exports = {
// Generates a token from supplied payload
issue(payload) {

Laravel allows you to use multiple Authentication types with specific guards.
In laravel 5.3 multiple authentication is little different from Laravel 5.2
I will explain how to implement multiauthentication feature in 5.3
First you need two different user Model
cp App/User.php App/Admin.php

Go to the repository you want to clone (something like: https://github.com/username/repo)
On the right, click on the green button named clone or download
A small window will appear, copy the url (something like: https://github.com/username/repo.git)
Open a terminal window on...
You can add partial mask on the column that will show few characters from te beginning and the end of the string and show mask instead of the characters in the middle:
ALTER TABLE Company
ALTER COLUMN Phone ADD MASKED WITH (FUNCTION = 'partial(5,"XXXXXXX",2)')
In the parameters of th...
If you add default mask on the column, instead of actual value in SELECT statement will be shown mask:
ALTER TABLE Company
ALTER COLUMN Postcode ADD MASKED WITH (FUNCTION = 'default()')
You can grant in-privileged users right to see unmasked values using the following statement:
GRANT UNMASK TO MyUser
If some user already has unmask permission, you can revoke this permission:
REVOKE UNMASK TO MyUser
Password Based Key Derivation can be used both for deriving an encryption key from password text and saving a password for authentication purposes.
There are several hash algorithms that can be used including SHA1, SHA256, SHA512 which are provided by this example code.
The rounds parameter is use...
See Swift 3 example for usage information and notes
func pbkdf2SHA1(password: String, salt: [UInt8], keyCount: Int, rounds: Int) -> [UInt8]? {
return pbkdf2(CCPBKDFAlgorithm(kCCPRFHmacAlgSHA1), password:password, salt:salt, keyCount:keyCount, rounds:UInt32(rounds))
}
func pbkdf2SHA256(p...
We initialize the data we want to interpolate:
x = 0:0.5:10;
y = sin(x/2);
This means the underlying function for the data in the interval [0,10] is sinusoidal. Now the coefficients of the approximating polynómials are being calculated:
p1 = polyfit(x,y,1);
p2 = polyfit(x,y,2);
p3 = polyfit(...
Func<int, int> add1 = i => i + 1;
Func<int, int, int> add = (i, j) => i + j;
// Behaviourally equivalent to:
int Add1(int i)
{
return i + 1;
}
int Add(int i, int j)
{
return i + j;
}
...
Console.WriteLine(add1(42)); //43
Console.WriteLine(Add1(42));...

Texas Instruments' (TI) CC26XX series SoCs are readily available wireless MCUs targeting Bluetooth Low Energy (BLE) applications. Along with the MCUs, TI offers a full-fledged software stack that provides necessary API and sample codes to help quickly get developers started with the to...
To install/update MVC version, follow these steps:
In visual studio, open the Package Manager console (use CTRL + Q, and type package manager console)
In the console appearing, enter the following after the console cursor showing PM>:

A decision tree is a classifier which uses a sequence of verbose rules (like a>7) which can be easily understood.
The example below trains a decision tree classifier using three feature vectors of length 3, and then predicts the result for a so far unknown fourth feature vector, the so called te...

Determine the number of PRF rounds to use for a specific delay on the current platform.
Several parameters are defaulted to representative values that should not materially affect the round count.
