[Winform]一个简单的账户管理工具

最近一直觉得注册的账户越来越多，帐号密码神马的容易弄混。自己就折腾了一个简单的账户管理工具，其实实现也挺简单，将每个账户的密码及相关密码提示信息，经aes算法加密之后保存到数据库，当前登录用户可以查询自己的账户信息，而不是别人的。界面如下：

数据表sql语句：

 1 GO
 2 
 3 /****** Object:  Table [dbo].[tb_Account]    Script Date: 10/23/2013 14:00:39 ******/
 4 SET ANSI_NULLS ON
 5 GO
 6 
 7 SET QUOTED_IDENTIFIER ON
 8 GO
 9 
10 SET ANSI_PADDING ON
11 GO
12 
13 CREATE TABLE [dbo].[tb_Account](
14     [typeId] [int] NOT NULL,
15     [Id] [int] IDENTITY(1,1) NOT NULL,
16     [userId] [int] NOT NULL,
17     [AcountName] NVARCHAR(50)NOT NULL,
18     [AcountMessage] [nvarchar](100) NULL,
19     [Pwd] [varchar](50) NOT NULL
20 ) ON [PRIMARY]
21 
22 GO
23 
24 SET ANSI_PADDING OFF
25 GO

 1 USE AcountManager
 2 GO
 3 
 4 /****** Object:  Table [dbo].[tb_type]    Script Date: 10/23/2013 14:00:58 ******/
 5 SET ANSI_NULLS ON
 6 GO
 7 
 8 SET QUOTED_IDENTIFIER ON
 9 GO
10 
11 CREATE TABLE [dbo].[tb_type](
12     [typeName] [nvarchar](50) NOT NULL,
13     [Id] [int] IDENTITY(1,1) NOT NULL
14 ) ON [PRIMARY]
15 
16 GO

 1 USE AcountManager
 2 GO
 3 
 4 /****** Object:  Table [dbo].[tb_Account]    Script Date: 10/23/2013 14:00:39 ******/
 5 SET ANSI_NULLS ON
 6 GO
 7 
 8 SET QUOTED_IDENTIFIER ON
 9 GO
10 
11 SET ANSI_PADDING ON
12 GO
13 
14 CREATE TABLE [dbo].[tb_Account](
15     [typeId] [int] NOT NULL,
16     [Id] [int] IDENTITY(1,1) NOT NULL,
17     [userId] [int] NOT NULL,
18     [AcountMessage] [nvarchar](100) NULL,
19     [Pwd] [varchar](50) NOT NULL
20 ) ON [PRIMARY]
21 
22 GO
23 
24 SET ANSI_PADDING OFF
25 GO

有个小工具，总比放在文本文件中好些，管理起来也方便点，关于密码等信息，也是经过md5或者aes加密算法处理的。
