(PHP ActiveX) Hash (Digest) a String

Hash the bytes of a string.

Chilkat ActiveX Downloads ActiveX for 32-bit and 64-bit Windows Note: The php_com_dotnet.dll may need to be enabled inside of php.ini.

<?php

// For versions of Chilkat < 10.0.0, use new COM('Chilkat_9_5_0.Chilkat.StringBuilder')
$sb = new COM("Chilkat.StringBuilder");

$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";
