数据加密用C#做的加密程序,望各位多提问题

using System;
using System.IO;
using System.Security.Cryptography;
using System.Text;

namespace DataCryptography
{
	/// <summary>

	public class HashMethod
	{

		/// <summary>

		public HashMethod()
		{
			HashCryptoService = new SHA1Managed();
		}
		/// <summary>

		/// <param name="Source">待加密的串</param>
		/// <returns>经过加密的串</returns>
		public string Encrypto(string Source)
		{
			byte[] bytIn = UTF8Encoding.UTF8.GetBytes(Source);
			byte[] bytOut = HashCryptoService.ComputeHash(bytIn);
			return Convert.ToBase64String(bytOut);
		}
	}
