(PHP Extension) Calculate MD5 Hash of File (or SHA1, SHA256, and other hash algorithms)Demonstrates how to calculate a hash for a file's contents.
<?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 assumes the Chilkat API to have been previously unlocked. // See Global Unlock Sample for sample code. $crypt = new CkCrypt2(); // Set the name of the hash algorithm. // Other choices include "sha1", "sha256", "sha384", "sha512", "md2", "md5", and "haval". $crypt->put_HashAlgorithm('md5'); // EncodingMode specifies the encoding of the hash output. // It may be "hex", "url", "base64", or "quoted-printable". $crypt->put_EncodingMode('hex'); // Files of any type may be hashed -- it doesn't matter // if the file is binary or text... $hashStr = $crypt->hashFileENC('/temp/something.dat'); if ($crypt->get_LastMethodSuccess() != true) { print $crypt->lastErrorText() . "\n"; exit; } print $hashStr . "\n"; ?> |
