You encrypt sensitive database fields in Rails by configuring Active Record Encryption on specific model attributes, ensuring data is encrypted at rest to prevent unauthorized access to PII or financial details.

Deterministic encryption in Active Record produces the same ciphertext for identical input strings, allowing encrypted fields to be queried or filtered. Non-deterministic encryption generates different ciphertext each time, providing stronger security but preventing database searches.

Migrating existing unencrypted data to encrypted fields in Rails requires a seamless migration process supported by Active Record Encryption. This ensures existing records are safely transitioned to the new encryption format without data loss.

Yes, you can search or filter encrypted database columns in Rails by using deterministic encryption. This method ensures identical plaintext values produce the same ciphertext, enabling standard query operations on encrypted attributes.

You manage and rotate encryption keys for Active Record by following secure key management guidance, which covers generating, storing, and rotating keys to maintain data security and compliance over time.

Yes, Active Record encryption works for privacy compliance by encrypting sensitive data at rest, such as social security numbers and email addresses, to prevent unauthorized access and meet regulatory requirements.
