如何将HEX字符串转换为普通文本字符串C＃ [英] How to convert HEX string to normal text string C#

问题描述

我们有一个keyMaterial HEX字符串。它看起来像这样

453F1287225ED9971D389A35F8D1032E7748DD0B88302F7C6C194626D4C8659B000000000E800000000200002000000047C2CA7B9A1F1C343CA228CC314A42F063A240E17624F886AF6CE9A135CAF65310000000D30489E536548F129E43240A26344811400000009EE2F5549B1447548ADADDD60A212C22DC2F9B2DC67D8E567B48B3847A525244A2F575AAFFB3AECD0385612BE7C38CA403BE6B5DFA8BEDEFBFA35C5ECC1818AB

您可以看到整个文件。我们如何将这个HEX代码转换为使用C＃的普通文本字符串？我在C ++上有一些例子，它没有帮助我。你可以给一个建议吗？

这个字符串的编码是16291388（但它不是解决问题的方法）

解决方案

如果您查看OP的原始文件，他正尝试解码无线配置文件的keyMaterial。

这个数据不仅仅是用十六进制编码的，它也是加密的，这就是为什么把它转换成字符串会导致无意义的数据。

这些数据是经过加密的，因此您不能将其解码为字符串。

We have a keyMaterial HEX string. It looks like this

453F1287225ED9971D389A35F8D1032E7748DD0B88302F7C6C194626D4C8659B000000000E800000000200002000000047C2CA7B9A1F1C343CA228CC314A42F063A240E17624F886AF6CE9A135CAF65310000000D30489E536548F129E43240A26344811400000009EE2F5549B1447548ADADDD60A212C22DC2F9B2DC67D8E567B48B3847A525244A2F575AAFFB3AECD0385612BE7C38CA403BE6B5DFA8BEDEFBFA35C5ECC1818AB

You can see the whole file. How can we translate this HEX code to normal text string with C#? I have some examples on C++, it hasn't helped me. Can you give an advise?

THE ENCODING OF THIS STRING IS 16291388 (but it's not a solution of the problem)

解决方案

If you look at the OP's original file he is trying to decode the keyMaterial of a wireless profile.

This data is not just encoded in hex, it is also encrypted which is why just converting it to a string results in nonsensical data.

<WLANProfile xmlns="http://www.microsoft.com/networking/WLAN/profile/v1">

            </sharedKey>
        </security>
    </MSM>
</WLANProfile>

This data is encrypted so you cannot just decode it into a string.
