[英]How do I generate IIS machineKey from inside code?
I want random values for this web.config section: 我想要此web.config部分的随机值:
<machineKey validation="HMACSHA512" decryption="AES"
validationKey="I NEED VALUE FOR THIS"
decryptionKey="SOME KEY" />
I see that IIS Manager can generate values but in the version I have it has no option for "HMACSHA512" in the dropdown. 我看到IIS管理器可以生成值,但是在我拥有的版本中,下拉菜单中没有用于“ HMACSHA512”的选项。 So I need some other way. 所以我需要其他方法。
I could write some C# code for that but what should it do exactly? 我可以为此编写一些C#代码,但是它应该做什么呢? Should it just generate a long enough random number and format that? 它应该生成足够长的随机数和格式吗?
Do I just use RNGCryptoServiceProvider
class and generate an appropriately long byte array and then format that as hex? 我是否只使用RNGCryptoServiceProvider
类并生成适当的长字节数组,然后将其格式化为十六进制? Will that do? 可以吗?

Pretty much. 差不多了 That's what the .NET Framework is doing when you set it to AutoGenerate
. 这就是.NET Framework在将其设置为AutoGenerate
时所做的事情 。
You can use RNGCryptoServiceProvider
to generate an hex value with an appropriate length. 您可以使用RNGCryptoServiceProvider
生成具有适当长度的十六进制值。 HMACSHA512 uses a 512-bit value, which is 64-bytes, or 128 hex characters. HMACSHA512使用512位值,即64字节或128个十六进制字符。 So we can do something like this: 所以我们可以做这样的事情:
var rng = System.Security.Cryptography.RandomNumberGenerator.Create();
var buffer = new byte[64];
rng.GetBytes(buffer);
var hmacKey = BitConverter.ToString(buffer).Replace("-", "");
