SQLCipher

As explained in .NET MAUI in Action

SQLCipher is an SQLite-compatible database library that encrypts database contents and transparently decrypts them during access.

SQLCipher extends SQLite-based storage with encryption, handling database encryption and decryption transparently during access. In a .NET MAUI app, it protects confidential local data while SQLite-net provides the database API. section 3.3

A practical SQLCipher setup combines these pieces:

  • Add the sqlite-net-pcl and sqlite-net-sqlcipher NuGet packages. section 3.3
  • Let .NET MAUI SecureStorage preserve the database key through OS-managed protection. section 3.3

Encrypted MauiTodo database

A MauiTodo application stores confidential to-do items in SQLite. SQLite-net maps the TodoItem POCO to database data, while SQLCipher encrypts the database and SecureStorage supplies the key.

How .NET MAUI in Action covers it

How deep it goes
Explains transparent encryption, package installation, key storage, and encrypted connection construction without detailing cryptographic internals.
Examples
Uses the MauiTodo app, TodoItem model, encrypted database path, and SecureStorage-managed key.
What it assumes
Assumes basic .NET MAUI project creation and C# data-model familiarity while building the SQLite persistence flow from a POCO.
What you can do after
Configure SQLite-net and SQLCipher to persist encrypted application data in a .NET MAUI app.
How it connects
Connects SQLCipher with SQLite, SQLite-net, SecureStorage, NuGet packages, and .NET MAUI.
