请教,怎么写PHP加密算法
请问,如何写PHP加密算法
看到有些PHP代码里全是经过加密后的乱码
那么执行是,是怎么处理的呢
我看到base64 好像只能加密单个字符,如果是一篇网页的话要如何加密呢
运行时又是如何还原呢?
------解决方案--------------------
base64 不是只加密单个字符
- PHP code
string base64_encode ( string $data ) base64_encode() returns 使用 base64 对 data 进行编码。设计此种编码是为了使二进制数据可以通过非纯 8-bit 的传输层传输,例如电子邮件的主体。 Base64-encoded 数据要比原始数据多占用 33% 左右的空间。 Example #1 base64_encode() 示例 <?php $str = 'This is an encoded string'; echo base64_encode($str); ?> 此示例将显示: VGhpcyBpcyBhbiBlbmNvZGVkIHN0cmluZw== <div class="clear"> </div>
