Chilkat PHP Downloads PHP Extension for Windows, Linux, MacOS, Alpine Linux, Solaris

<?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");

$sb = new CkStringBuilder();

$sb->Append('Hello World');

// Hashing algorithms (i.e. digest algorithms) operate on raw bytes.
// Therefore, we must specify the character encoding (utf-8, utf-16, iso-8859-1, etc.) to be used when hashing.

// Get the SHA256 hash in hex
$sha256_hex = $sb->getHash('sha256','hex','utf-8');
print 'SHA256: ' . $sha256_hex . "\n";

// Get the SHA384 hash in hex lowercase
$sha384_hex = $sb->getHash('sha384','hex_lower','utf-8');
print 'SHA384: ' . $sha384_hex . "\n";

// Get the SHA512 hash in base64
$sha512_base64 = $sb->getHash('sha512','base64','utf-8');
print 'SHA512: ' . $sha512_base64 . "\n";

// Get the SHA1 hash in hex lowercase
$sha1_hex = $sb->getHash('sha1','hex_lower','utf-8');
print 'SHA1: ' . $sha1_hex . "\n";

// Get the CRC8 digest in decimal
$crc8_decimal = $sb->getHash('crc8','decimal','utf-8');
print 'CRC8: ' . $crc8_decimal . "\n";
