SQLite has hooks built-in for encryption which are not used in the normal distribution, but here are a few implementations I know of:
- SEE – The official implementation.
- wxSQLite – A wxWidgets style C++ wrapper that also implements SQLite’s encryption.
- SQLCipher – Uses openSSL’s libcrypto to implement.
- SQLiteCrypt – Custom implementation, modified API.
- botansqlite3 – botansqlite3 is an encryption codec for SQLite3 that can use any algorithms in Botan for encryption.
- sqleet – another encryption implementation, using ChaCha20/Poly1305 primitives. Note that wxSQLite mentioned above can use this as a crypto provider.
The SEE and SQLiteCrypt require the purchase of a license.
Disclosure: I created botansqlite3.
