C＃相當於Java的KDFCounterBytesGenerator（從BouncyCastle的）

Question

我想端口這段代碼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); 

但我無法找到C＃BouncyCastle的庫中的任何等價類。
有什麼建議嗎？

編輯： 我從Java源代碼移植的KDFCounterBytesGenerator它工作得很好..

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

你應該能夠通過的NuGet來安裝它，然後相應地引用它：

// 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);
