关于php如何解密.net加密后数据库里面的内容和文件
回复讨论(解决方案)
什么样的数据?至少应截个图
转化后的东西太长,所以没有截图
这个是我摘的某个数据(论坛字符限制,只发一小部分)

0x424D465C0C0......
这样表示的是一个十六进制数的字符串
你可在读取后去掉前面的 0x 后,用 pack 函数还原出原始内容
$s = pack('H*', substr($s, 2));
你示例的是一个 BMP 图片数据
这个我以前试看到过,不过当时用的是C,现在我用H或者C都是同样的乱码问题,始终解决不了,网上资料介绍说是编码问题,我主要的编码都试过了,还是不行,不知道咋办
虽然没有解决问题,还是谢谢你
尽管你只贴出了数据片段,但仍然能看到你的数据时一个 BMP 图片
