SQLCipher

SQLCipher is a standalone, open-source fork of SQLite that provides full database encryption using 256-bit AES.

SQLCipher is the go-to solution for securing data in mobile, embedded, and desktop applications. It's a specialized build of the SQLite library, offering transparent, on-the-fly encryption for the entire database file. The core security is built on strong, industry-standard cryptography: 256-bit Advanced Encryption Standard (AES) in CBC mode, paired with a robust key derivation function (PBKDF2-HMAC-SHA512, defaulting to 256,000 iterations). Maintained by Zetetic, LLC, it ensures data protection against compromise, making it a standard choice for sensitive data in regulated industries like financial services and healthcare.
