[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：

 GO /****** Object:  Table [dbo].[tb_Account]    Script Date: 10/23/2013 14:00:39 ******/
 SET ANSI_NULLS ON
 GO SET QUOTED_IDENTIFIER ON
 GO SET ANSI_PADDING ON
 GO CREATE TABLE [dbo].[tb_Account](
     [typeId] [int] NOT NULL,
     [Id] [int] IDENTITY(,) NOT NULL,
     [userId] [int] NOT NULL,
     [AcountName] NVARCHAR()NOT NULL,
     [AcountMessage] [nvarchar]() NULL,
     [Pwd] [varchar]() NOT NULL
 ) ON [PRIMARY] GO SET ANSI_PADDING OFF
 GO

 USE AcountManager
 GO /****** Object:  Table [dbo].[tb_type]    Script Date: 10/23/2013 14:00:58 ******/
 SET ANSI_NULLS ON
 GO SET QUOTED_IDENTIFIER ON
 GO CREATE TABLE [dbo].[tb_type](
     [typeName] [nvarchar](50) NOT NULL,
     [Id] [int] IDENTITY(1,1) NOT NULL
 ) ON [PRIMARY] GO

 USE AcountManager
 GO /****** Object:  Table [dbo].[tb_Account]    Script Date: 10/23/2013 14:00:39 ******/
 SET ANSI_NULLS ON
 GO SET QUOTED_IDENTIFIER ON
 GO SET ANSI_PADDING ON
 GO CREATE TABLE [dbo].[tb_Account](
     [typeId] [int] NOT NULL,
     [Id] [int] IDENTITY(1,1) NOT NULL,
     [userId] [int] NOT NULL,
     [AcountMessage] [nvarchar](100) NULL,
     [Pwd] [varchar](50) NOT NULL
 ) ON [PRIMARY] GO SET ANSI_PADDING OFF
 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。
