Overview

The module provides an extended set of cryptography primitives and algorithms for .NET.

ARC4

ARC4 (Alleged Rivest Cipher 4 also known as ARCFOUR or RC4) is a stream cipher. While it is remarkable for its simplicity and performance, nowadays its usage is limited due to discovered limitations and vulnerabilities.

Still, ARC4 may be a good enough fit for less sensitive tasks. For example, it can be used for communication with legacy or energy-constrained systems.

Example:

using Gapotchenko.FX.Security.Cryptography;

byte[] messageToEncrypt = ...;
byte[] key = ...;

// Encryption

byte[] encryptedMessage;

using (var arc4 = Arc4.Create())
{
    arc4.Key = key;

    var ms = new MemoryStream();
    using (var cryptoStream = new CryptoStream(ms, arc4.CreateEncryptor(), CryptoStreamMode.Write))
        cryptoStream.Write(messageToEncrypt, 0, messageToEncrypt.Length);

    encryptedMessage = ms.ToArray();
}

// Decryption

byte[] decryptedMessage;

using (var arc4 = Arc4.Create())
{
    arc4.Key = key;

    var ms = new MemoryStream();
    using (var cryptoStream = new CryptoStream(ms, arc4.CreateDecryptor(), CryptoStreamMode.Write))
        cryptoStream.Write(encryptedMessage, 0, encryptedMessage.Length);

    decryptedMessage = ms.ToArray();
}
