I have a database I encrypted using SQLite Encryption Extension being used with MobileServiceSQLiteStore.
Is there anyway to use DB Browser with SqlCipher to view the database. I have the key that was used to decrypt the database.
No, SQLCipher is not compatible with the SQLite Encryption Extension. You may be able to use a command line shell compiled with SQLite Encryption Extension support to open the database.

We are developing Xamarin.forms application and we have to encrypt our database.
While googling I found something is 'PRAGMA key'. When I started using this in my code then on opening the db file via any browser I get a dialog box to enter the Passphrase.
My question here is, does 'PRAGMA key' encrypt whole database or it just works like a password to open the database file.
Any help is greatly appreciated.
Without a version of SQLite that includes SQlite Encryption Extension (SEE), the pragma will be ignored.
With SEE included the entire database is encrypted. It is possible to put together code that could be used to encrypt specific columns without using SEE.
For SQLite db we can use SQLite Browser to do CRUD operations and view the .db file. Are there any interface to view the content of a Berkeley DB file?
Berkeley DB includes a sqlite library wrapper (it's exactly an sqlite API) that should work with your sqlite browser.
Note that not all Berkeley DB databases can be used under the sqlite layer: there are some constraints on the data storage if the sqlite wrapper is used.
Using db_dump will display the key -> value pairs in a Berkeley DB in hex.
What's the easiest way to backup/restore sqlite memory database to file database in Qt.
I think you will need to work with SQLite directly to do this. SQLite has an Online Backup API, the first example is backing up an in-memory database to a file database, so it should be possible to do what you need to do.
To get a sqlite3* database handle, get the driver (QSqlDatabase::driver) from the database then get the handle (QSqlDriver::handle). The example code in the Qt docs shows how to cast the QVariant into a sqlite3* handle.
I have a db file but I don't know whether it was created with System.Data.Sqlite or anything else. And I also don't know its password.
Is there any way I can know sqlite password and db file version?
Sqlite databases can be encrypted with an extension. If the database is not encrypted, the version number is in clearly indicated in the data file. If the database is encrypted, there is no way to recover the password practically.
Just wondering if it is possible to convert sql-server *.mdf file into sqlite file ?
There's a C# utility to automatically do the conversion from SQL Server DB to SQLite DB on CodeProject
