## Proprietary SQLite Extensions

The core SQLite library found on this website is in the public domain. But there also exist proprietary, licensed extensions to SQLite.

- The SQLite Encryption Extension (SEE) will read and write database files encrypted using 128-bit or 256-bit AES.

- The SQLite Compressed and Encrypted Read-Only Database (CEROD) extension will read a database file that is both compressed and encrypted.

- The ZIPVFS extension will both read and write database files that are both compressed and optionally encrypted using application-supplied compression and encryption routines.

- The Test Harness #3 (TH3) is an alternative set of test vectors for SQLite that verify the operation of SQLite in an as-deployed configuration on embedded platforms with 100% branch test coverage.
