How Can I Password-Protect a SQLite Database?

Securing Your SQLite Database: Password Protection

Data security is paramount, especially when dealing with sensitive information. This guide explains how to add password protection to your SQLite database.

Implementing Password Protection

SQLite offers a built-in mechanism for password protection. Here's how to implement it:

1. Establish a Connection: Create a new SQLite connection specifying your database file:

   <code class="language-csharp">SQLiteConnection conn = new SQLiteConnection("Data Source=MyDatabase.sqlite;Version=3;");</code>

2. Set the Password: Use the SetPassword method to establish the password:

   <code class="language-csharp">conn.SetPassword("password");</code>

3. Open the Connection: Open the connection to activate the password protection:

   <code class="language-csharp">conn.Open();</code>

Accessing the Protected Database

Accessing your password-protected database requires including the password in the connection string:

<code class="language-csharp">conn = new SQLiteConnection("Data Source=MyDatabase.sqlite;Version=3;Password=password;");
conn.Open();</code>

This prevents unauthorized access through common GUI database editors. However, remember that some advanced tools might still be able to decrypt the database if the password is provided.

Modifying or Removing the Password

You can easily modify or remove the password as needed. To change the password:

<code class="language-csharp">conn.ChangePassword("new_password");</code>

To remove the password entirely:

<code class="language-csharp">conn.ChangePassword(String.Empty);</code>

By employing this password protection, you significantly enhance the security of your SQLite database, even if the database file itself is compromised.
