MD5+salt加密

测试文档md5.php:

<?php
function do_hash($pwd){
  $salt ="lkdfl124g5dstg";  //自己随便输入盐值
  return md5($pwd.$salt);
}
$char="myblog";  //验证使用$salt_pwd = do_hash($_POST["password"])
$md5_char = md5($char); 
$salt_char = do_hash($char); //调用
echo "md5-char is: $md5_char;;;;;;";
echo "salt-char is: $salt_char";
?>
