使用C＃代码设置密码后，为什么不能打开Sqlite数据库？

Question

I have a SQLite database. I use C# code to set its password. It all goes well with no error. However, I cannot open it using "DB Browser For Sqlite" client.

Here is my c# code:

SQLiteConnection cnn = new SQLiteConnection(Config.ConnectionString);
cnn.Open();
cnn.ChangePassword(Config.DbPassword);
cnn.Close();
cnn.Dispose();

Here is the login picture:

Edit: If I use DB Browser for SQLite option "Set Encryption" then it works fine in both C# code and DB Browser for SQLite.

Answer 1

For anyone else facing this issue, I turns out SQL uses "SQLCipher only recognizes 256-bit AES" according to this link: github.com/sqlitebrowser/sqlitebrowser/wiki/Encrypted-Databases and System.Data.SQLite; uses a different encryption. So if you just want to encrypt your SQLite DB then using System.Data.SQLite is does the job. But if you want to specifically encrypt it with SQLCipher then use SQLitePCLRaw.bundle_sqlcipher package.
