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）
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

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
