SQLCipher encrypts SQLite data. Key management is as important as the database solution itself.
Evaluation approach
Do not embed keys in code. Coordinate database and key lifecycles during startup, backups, migrations and logout.
Application example
Test that switching accounts cannot reopen the previous database under the wrong account context.
Limits and considerations
Encryption does not prevent unauthorized queries while open or disclosures through logs.
The lifetime of an open connection
Queries still need business authorization after opening. Review connections and caches on logout; an encrypted file alone does not prevent displaying the previous user's records.
Checks and decisions
- Protect keys
- Test migration
- Limit plaintext exposure
