Usage

var str = "String to be compressed";
var strCompressed = Cipher.Compress(str);
var strDecompressed = Cipher.Decompress(strCompressed);

Cipher class

using System;
using System.IO;
using System.IO.Compression;
using System.Text;

public static class Cipher
{
    /// <summary>
    /// String compress
    /// </summary>

        {

        }

        using (var compressedStream = new MemoryStream())
        {
