PHP Extension

Example: Crypt2.GenRandomBytesENC method

Shows how to use the GenRandomBytesENC method to generate a specified number of random bytes and return them as a binary encoded string, such as in base64 or hex format. PHP Extension

<?php

include("chilkat.php");

$crypt = new CkCrypt2();

// Example of a some of the binary encodings supported by Chilkat.

// Internally uses the Fortuna cryptographically secure random number generation algorithm
// auto-seeded from a secure source of entropy that depends on the OS.

$crypt->put_EncodingMode('hex');
$s = $crypt->genRandomBytesENC(8);
print 'Uppercase Hex: ' . $s . "\n";

$crypt->put_EncodingMode('hex_lower');
$s = $crypt->genRandomBytesENC(8);
print 'Lowercase Hex: ' . $s . "\n";

$crypt->put_EncodingMode('base64');
$s = $crypt->genRandomBytesENC(8);
print 'Base64: ' . $s . "\n";

$crypt->put_EncodingMode('base64url');
$s = $crypt->genRandomBytesENC(8);
print 'Base64Url: ' . $s . "\n";

$crypt->put_EncodingMode('base58');
$s = $crypt->genRandomBytesENC(8);
print 'Base58: ' . $s . "\n";

$crypt->put_EncodingMode('base32');
$s = $crypt->genRandomBytesENC(8);
print 'Base32: ' . $s . "\n";

$crypt->put_EncodingMode('decList');
$s = $crypt->genRandomBytesENC(8);
print 'Decimal List: ' . $s . "\n";

// Sample Output:

// Uppercase Hex: 1BA0E87915C3B429
// Lowercase Hex: 1e1638a1c7996c58
// Base64: 1lV0I/su5lg=
// Base64Url: Zq7DU0nukLk
// Base58: foUVWUjAT6e
// Base32: LHV5RV4HRCLW2===
// Decimal List: 168,55,214,82,93,154,191,164
