简单的加密 [英] simple encryption
问题描述
嗨
我正在寻找加密的一些.net示例代码：我不想要任何花哨的东西，没有复杂的第三方组件，复杂的算法，原理的解释，或者;公钥/私钥混淆（似乎所有谷歌都可以提出） - 我只想要一个简单的例子，说明如何加密字符串，然后取回相同的字符串。我在MSDN上找到了一个例子，它涉及编译DLL然后在测试表单中使用它，但是大约每5次抛出一个异常，这对我来说不够好 - 我只需要它很简单。它不需要是对抗硬化的破解者的最先进的防御，主要是因为它不能从阅读它看 - 不是更多。但必须简单并且总是给予相同的回报。
任何人？

相同的字符串。我在MSDN上找到了一个例子，它涉及编译一个DLL，然后在测试表单中使用它，但是大约有五分之一它会抛出异常，这对我来说不够好 - 我只需要它很简单。它不需要是对抗强化的黑客攻击者的最先进的防御，主要是因为它不能从瞥见它 - 而不是更多。但必须简单并且总是给予相同的回复。
CryptoStream的文档给出了一个加密字节
数组的简单示例。要使用字符串，只需使用Encoding.UTF8.GetBytes
将字符串转换为字节数组，并将Encoding.UTF8.GetString转换为
，然后在解密后将其转换回来。

干杯快速响应。
但为什么选择UTF8？
以及文档中此示例的任何链接？

这是一种无损编码，适用于ASCII。如果你使用的是很多非ASCII的，那么使用Encoding.Unicode会有意义。
和文档中这个例子的任何链接？
什么，使用Encoding.UTF8？从来没听说过。加密
从根本上对二进制数据起作用，二进制数据和文本数据之间的转换与加密本身截然不同。

Hi
I''m looking for some .net example code on encryption: I don''t want anything fancy, no complex third party components with sophisticated algorithms, explanations of principle, or "public/private key" confusion (which seems to be all google can come up with) - I just want a SIMPLE example of how I can encrypt a string and then get back the SAME STRING. I found an example on MSDN which involves compiling a DLL then using it in a test form, but about 1 in 5 times it throws an exception, this isn''t good enough for me - I just need it to be simple. It doesn''t need to be state of the art defence against hardened crackers, mainly just so it can''t be read from glancing at it - not much more. But must be SIMPLE and ALWAYS GIVE THE SAME THING BACK.
Anyone?

The docs for CryptoStream give a simple example of encrypting a byte
array. To use strings instead, just use Encoding.UTF8.GetBytes to
transform the string into a byte array, and Encoding.UTF8.GetString to
transform it back after decrypting.

Cheers for the very quick response.
But why UTF8?
And any link to this example in the docs?

It''s a lossless encoding which is compact for ASCII. If you''re using a
lot of non-ASCII, it would make sense to use Encoding.Unicode instead.

What, to using Encoding.UTF8? Not that I know of. Encryption
fundamentally acts on binary data, and the conversion between binary
data and text data is quite distinct from encryption itself.
