使用asp.net提供的MD5實現加密計算

    protected void Page_Load(object sender, EventArgs e)
    {
        //myEditor.InnerHtml = CreateMD5("http://www.qk12333.com");
    }
    //使用MD5加密
    private string CreateMD5(string password)
    {
        MD5 md5 = new MD5CryptoServiceProvider();
        byte[] result = md5.ComputeHash(System.Text.Encoding.Default.GetBytes(password));
        return ConvertToHex(result).ToUpper();
    }
    private string ConvertToHex(byte[] bArr)
    {
        StringBuilder builder = new StringBuilder();
        for (int i = 0; i < bArr.Length; i++)
        {
            byte b = bArr[i];
            int value = (b & 0xFF) + (b < 0 ? 128 : 0);
            builder.Append(value < 16 ? "0" : "");
            builder.Append(value.ToString("x"));
        }
        return builder.ToString();

    }
