C＃相当于Java的KDFCounterBytesGenerator（从BouncyCastle的）

Question

我想端口这段代码C＃

byte[] result = new byte[length]; 
byte[] data = ...; 
byte[] key = ...; 

HMac hMac = new HMac(new SHA256Digest()); 
KDFCounterBytesGenerator g = new KDFCounterBytesGenerator(hMac); 
g.init(new KDFCounterParameters(key, data, 32)); 
g.generateBytes(result , 0, result .length); 

但我无法找到C＃BouncyCastle的库中的任何等价类。
有什么建议吗？

编辑： 我从Java源代码移植的KDFCounterBytesGenerator它工作得很好..

BouncyCastle has an equivalent library for C#应包含最如果不是所有的相同的功能，它的Java版本有一些小的语法差异：

你应该能够通过的NuGet来安装它，然后相应地引用它：

// Using statements (for BouncyCastle) 
using Org.BouncyCastle.Crypto.Digests; 
using Org.BouncyCastle.Crypto.Generators; 

// Define your byte[]s 
byte[] result = new byte[1]; 
byte[] data = new byte[2]; 
byte[] key = new byte[3]; 

// Build your HMac, Generator and generate your bytes 
HMac hMac = new HMac(new Sha256Digest()); 
Kdf1BytesGenerator g = new Kdf1BytesGenerator(hMac.GetUnderlyingDigest()); 
g.Init(new Org.BouncyCastle.Crypto.Parameters.KdfParameters(key, data)); 
g.GenerateBytes(result, 0, result.Length);
