压缩（GZip/Brotli）和加密（Aes）问题

对于压缩和加密问题，可以使用以下代码实现：

1. GZip压缩和解压缩代码示例：

// 压缩函数 public static byte[] Compress(byte[] data) { using (var output = new MemoryStream()) { using (var gzip = new GZipStream(output, CompressionMode.Compress)) { gzip.Write(data, 0, data.Length); }

    return output.ToArray();
}

}

// 解压函数 public static byte[] Decompress(byte[] data) { using (var input = new MemoryStream(data)) { using (var gzip = new GZipStream(input, CompressionMode.Decompress)) { using (var output = new MemoryStream()) { gzip.CopyTo(output); return output.ToArray(); } } } }

2. Brotli压缩和解压缩代码示例：

// 压缩函数 public static byte[] Compress(byte[] data) { using (var output = new MemoryStream()) { using (var brotli = new BrotliStream(output, CompressionMode.Compress)) { brotli.Write(data, 0, data.Length); }

    return output.ToArray();
}

}

// 解压函数 public static byte[] Decompress(byte[] data) { using (var input = new MemoryStream(data)) { using (var brotli = new BrotliStream(input, CompressionMode.Decompress)) { using (var output = new MemoryStream()) { brotli.CopyTo(output); return output.ToArray(); } } } }

3. Aes加密和解密代码示例：

// 加密函数 public static byte[] Encrypt(byte[] data, string password) { using (var aes = Aes.Create()) { aes.Key = GenerateKey(password, aes.KeySize); aes.IV = GenerateIV(aes.BlockSize);

    using (var encryptor = aes.CreateEncryptor())
    {
        using (var input = new MemoryStream(data))
        {
            using (var output = new MemoryStream())
            {
                using (var cryptoStream =
