(PHP Extension) Generating Repeatable Random Data for Testing/Debugging

Demonstrates how to use the Fortuna PRNG to generate random-looking but repeatable non-random data for the purpose of testing and debugging.

PHP Extension for Windows, Linux, and MAC OS X

<?php

// The version number (9_5_0) should match version of the Chilkat extension used, omitting the micro-version number.
// For example, if using Chilkat v9.5.0.48, then include as shown here:
include("chilkat_9_5_0.php");

//  All Chilkat classes can be unlocked at once at the beginning of a program
//  by calling UnlockBundle.  It requires a Bundle unlock code.
$chilkatGlob = new CkGlobal();
$success = $chilkatGlob->UnlockBundle('Anything for 30-day trial.');
if ($success != true) {
    print $chilkatGlob->lastErrorText() . "\n";
    exit;
}

$fortuna = new CkPrng();

//  Normally an application would seed the PRNG with entropy from
//  some real random source.  However, sometimes we want the same
//  random sequence of bytes for testing and debugging purposes.
//  This a reason why GetEntropy and AddEntropy are two different methods.
//  An application could omit the call to GetEntropy, and instead pass
//  non-random data to AddEntropy. For example:

//  Seed the PRNG with non-entropy, so we get a repeatable sequence.
//  Note: AddEntropy can be called any number of times.
$success = $fortuna->AddEntropy('01020304','hex');
$success = $fortuna->AddEntropy('hello world','ascii');

//  Generate some random data:
$strRandHex = $fortuna->genRandom(16,'hex');
$strRandBase64 = $fortuna->genRandom(22,'base64');
$strRandBase58 = $fortuna->genRandom(32,'base58');

print 'hex random bytes: ' . $strRandHex . "\n";
print 'base64 random bytes: ' . $strRandBase64 . "\n";
print 'base58 random bytes: ' . $strRandBase58 . "\n";

//  Try it again with a different object to verify that the same results are obtained:
$fortuna2 = new CkPrng();

$success = $fortuna2->AddEntropy('01020304','hex');
$success = $fortuna2->AddEntropy('hello world','ascii');

$strRandHex = $fortuna2->genRandom(16,'hex');
$strRandBase64 = $fortuna2->genRandom(22,'base64');
$strRandBase58 = $fortuna2->genRandom(32,'base58');

print 'hex random bytes: ' . $strRandHex . "\n";
print 'base64 random bytes: ' . $strRandBase64 . "\n";
print 'base58 random bytes: ' . $strRandBase58 . "\n";
