Had 2.11 ver with encrypted db with password without any fake password, delete db options...
Installed latest version.
Three attempts, my db all with my sensitive data gone.
All undelete solutions bring corrupted database as result. Repair key is not working.
1.Create test db with password and encryption in 2.11
2. Open it in 2.2 with 3 wrong password attempts.
3 Good buy your test db forever.
