Hi @chad

It would be difficult to downgrade because the default security settings for SQLCipher 4 are not available in SQLCipher 3.x (i.e. PBKDF2-HMAC-512 and HMAC-512). What problems are you facing with your version of SQLCipher?

Those are all the old artifacts for SQLCipher for Android. You will want to remove those old files if you are upgrading. The newer version of SQLCipher for Android can be included with an application using the AAR reference within a Gradle project file. You can follow the instructions [here](https://www.zetetic.net/sqlcipher/sqlcipher-for-android/) for integration guidance.
