A simple and quite fast (10ms/Mb) way to generate checksums used with the popular SFV (Simple File
Verification) format. strtoupper() isn't really needed, but the output looks better this way ;)
<?php
function generate_sfv_checksum($filename) {
$sfv_checksum = strtoupper(dechex(crc32(file_get_contents($filename))));
return $sfv_checksum;
}
?>
