PHP常用加密解密方法作者/上善若水
1.md5(string $str,bool $flag = false);
$flag = false 默认返回32位的16进至数据散列值
【php加解密的数据 php des解密】 $flag = true返回原始流数据
2.sha1($string,$flag = false)
$flag = false 默认返回40位的16进至数据散列值
true返回原始流数据
3.hash(string $algo,srting $str,bool $flag);
$algo : 算法名称，可通过hash_algos()函数获取所有hash加密的算法
如：md5,sha1等，采用md5,sha1加密所得结果和1,2两种方式结 果相同 。
$flag = false 默认返回16进至的数据散列值 ， 具体长度根据算法不同
