Research direction
Investigate the SQLite3MultipleCiphers extension to understand the current cipher support. Look for where the cipher is selected (likely in the encryption module). Then design a configuration interface (e.g., a PRAGMA statement) to allow users to choose a cipher. Consider issues of compatibility and performance.
