JAVA to C# code conversion

I have one JAVA Desktop application I need to convert one specific functionality of it in to C#.I'll provide the java code and all other required data. The ultimate goal is the c# application must generate the same output JAVA application generates. The code JAVA code is as follows: protected void init() { byte[] key = getPlatformHook().generateKey(getSeedFile()); [login to view URL] = new byte[32]; [login to view URL] = new byte[[login to view URL] - [login to view URL]]; [login to view URL](key, 0, [login to view URL], 0, [login to view URL]); [login to view URL](key, [login to view URL], [login to view URL], 0, [login to view URL]); [login to view URL] = null; [login to view URL] = [login to view URL]; [login to view URL] = 0; loadSeed(); } protected void decryptSeed(byte[] encryptedSeed) throws IOException { decryptSeed(encryptedSeed, [login to view URL], [login to view URL]); } protected void decryptSeed(byte[] encryptedSeed, byte[] encryptionkey, byte[] initVector) throws IOException { byte[] decryptedSeed = new byte[[login to view URL]]; RijndaelCFB cipher = new RijndaelCFB(encryptionkey, initVector); [login to view URL](encryptedSeed, decryptedSeed); byte[] seed = new byte[20]; DataInputStream ds = new DataInputStream(new ByteArrayInputStream(decryptedSeed)); [login to view URL](seed); [login to view URL] = [login to view URL]([login to view URL]() & 0xFF); [login to view URL] = [login to view URL](); byte[] digest = new SHA1().digest(seed); for (int i = [login to view URL] + 1 + 4; i < [login to view URL]; i++) { if (decryptedSeed[i] != digest[(i - [login to view URL] - 1 - 4)]) { [login to view URL] = true; } } setSeed(seed); } From above code I need to convert the decryptSeed to c# the file with encrypted data which this file decryptes is attached in attachments. The name of file is [login to view URL]
