(PHP Extension) Hash the Contents of a String (SHA256 and other hash algorithms)Demonstrates how to hash the contents of a string using SHA256, SHA384, SHA512, MD2, MD5, HAVAL, RIPEMD, etc.
<?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"); // This example requires the Chilkat Crypt API to have been previously unlocked. // See Unlock Chilkat Crypt for sample code. $crypt = new CkCrypt2(); // Choose the hash algorithm. // Can be "sha1", "sha256", "sha384", "sha512", "md2", "md5", "haval", "ripemd128", "ripemd160","ripemd256", or "ripemd320". $crypt->put_HashAlgorithm('sha256'); // The byte representation of the string matters when hashing. // Tell Chilkat that we want to use the utf-8 byte representation. $crypt->put_Charset('utf-8'); $hashBytes = new CkByteData(); $success = $crypt->HashString('They who can give up essential liberty to obtain a little temporary safety deserve neither liberty nor safety.',$hashBytes); // Let's examine the hash as a hex string. $sb = new CkStringBuilder(); $sb->AppendEncoded($hashBytes,'hex'); print 'SHA256 hash = ' . $sb->getAsString() .
