PHP中对各种加密算法、Hash算法的速度测试对比代码

2014-07-08 08:39 751 查看

PHP 的Hash算法是比较常用的，现在的MD5有时候不太安全，就得用到Hash_algos()中的其它算法，下面进行了一个性能的比较。

php代码：

define('testtime', 50000);
$algos = hash_algos();
foreach($algos as $algo) {
$st = microtime();
for($i = 0; $i < testtime; $i++) {
hash($algo, microtime().$i);
}
$et = microtime();
list($ss, $si) = explode(' ', $st);
list($es, $ei) = explode(' ', $et);
$time[$algo] = $ei + $es - $si - $ss;
}
asort($time, SORT_NUMERIC);
echo "";
print_r($time);
