   使用数据库密码加密 Access 数据库

  Access 中的加密工具合并了两个旧工具(编码和数据库密码),,并加以改进。使用数据库密码来加密数据库时,所有其他工具都无法读取数据,并强制用户必须输入密码才能使用数据库。在 Access 2010 中应用的加密所使用的算法比早期版本的 Access 使用的算法更强。

  注释 如果在 Access 2007 中使用了数据库密码来加密数据库,则可能需要切换到新的加密技术,这有助于提供更高的安全性。

  将加密的 Access 2007 数据库切换到新的加密技术

  若要切换到新的加密技术,请删除当前的数据库密码,然后重新添加此密码。

  通过使用数据库密码进行加密

  在独占模式下打开要加密的数据库。

  在独占模式下打开数据库

  在“文件”选项卡上,单击“打开”。

  在“打开”对话框中,通过浏览找到要打开的文件,然后选择文件。

  单击“打开”按钮旁边的箭头,然后单击“以独占方式打开”。

  在“文件”选项卡上,单击“信息”,再单击“用密码进行加密”。

  随即出现“设置数据库密码”对话框。

  在“密码”框中键入密码,然后在“验证”字段中再次键入该密码。

  注释 使用由大写字母、小写字母、数字和符号组合而成的强密码。弱密码不混合使用这些元素。例如,Y6dh!et5 是强密码;House27 是弱密码。密码长度应大于或等于 8 个字符。最好使用包括 14 个或更多个字符的密码。有关详细信息,请参阅使用强密码有助于保护个人信息。记住密码很重要。如果忘记了密码,Microsoft 将无法找回。最好将密码记录下来,保存在一个安全的地方,这个地方应该尽量远离密码所要保护的信息。

  单击“确定”。

  解密并打开数据库

  以通常打开其他任何数据库的方式打开加密的数据库。

  随即出现“要求输入密码”对话框。

  在“输入数据库密码”框中键入密码,然后单击“确定”。

  去掉密码

  在“文件”选项卡上,单击“信息”,再单击“解密数据库”。

  将出现“撤消数据库密码”对话框。

  在“密码”框中键入密码,然后单击“确定”。

Adding MySQL users through the PHP web interface can use MySQLi extensions. The steps are as follows: 1. Connect to the MySQL database and use the MySQLi extension. 2. Create a user, use the CREATEUSER statement, and use the PASSWORD() function to encrypt the password. 3. Prevent SQL injection and use the mysqli_real_escape_string() function to process user input. 4. Assign permissions to new users and use the GRANT statement.
