SQLCipher is a security extension for SQLite that allows you to create encrypted databases. It's essentially a modified version of SQLite that adds a layer of encryption to protect your data. Here's a breakdown of what SQLCipher offers: * **Encryption:** SQLCipher encrypts the entire database file using 256-bit AES encryption, a strong encryption standard. This means even if someone gets their hands on your database file, they won't be able to access the data without the encryption key. * **Transparent encryption:** The encryption process is handled in the background, so you can use SQLCipher just like regular SQLite with minimal changes to your code. SQLCipher is a useful tool for developers who need to store sensitive data in SQLite databases on mobile devices or other platforms.
