PHP Resonantcore\Lib Secure Examples

Example #1

File: SecureTest.php Project: resonantcore/lib

 public function testBias()
 {
     $this->markTestSkipped('This test can fail randomly; only enable it when needed.');
     // Populate:
     $buffer = array_fill(0, 10, 0);
     // Perform the experiment:
     for ($i = 0; $i < 5000; ++$i) {
         // Increase a random index by 1
         $j = \Resonantcore\Lib\Secure::random(0, 9);
         ++$buffer[$j];
     }
     var_dump($buffer);
     // Analyze the results:
     for ($i = 0; $i < 10; ++$i) {
         // If any of these are 0, then our RNG is failing us
         $this->assertNotEquals($buffer[$i], 0);
     }
 }

Example #2

File: CSRF.php Project: resonantcore/lib

  * Generate, store, and return the index and token
  * 
  * @return array [string, string]
  */

     self::recycleTokens();
     return [$index, $token];
 }
