在 C# 中设置和更改 SQLite 数据库密码

Question

I'm implementing SQLite functionality in my code, where I can create an SQLite database file and communicate with it. I can't, however, password protect it. I've seen a lot of solutions, for example:

conn = new SQLiteConnection(connectionString);
conn.ChangePassword("Password");

However, the methods ChangePassword() or SetPassword() doesn't exist in System.Data.SQLite.SQLiteConnection, so it won't work. So my question is, am I missing something?

I'm using the latest release of the official SQLite Nuget Package.

The method is not supported in the .net Core (.net Standard) version of the library.

For connecting to a password-protected database, specify the password in the connection string. Use the SQLiteConnectionStringBuilder.Password or SQLiteConnectionStringBuilder.HexPassword properties.

For setting a password or changing the password, issue an sql pragma statement.

pragma key='NewPassword'

or

pragma rekey='NewPassword'
