If you prefer environment variables, you can set them in config/application.rb : active_record_encryption_deterministic_key

find_by or uniqueness validations while keeping the data encrypted at rest. Ruby on Rails Guides +4 Configuration You must define this key in your application's credentials or environment configuration for deterministic encryption to function.

Copied to clipboard Usage in Models Once configured, you can enable it on specific attributes: Ruby on Rails Guides ruby class User < ApplicationRecord # Deterministic encryption allows User.find_by(email: "example@test.com") encrypts :email, deterministic: true end Use code with caution.

Because the deterministic key produces identical ciphertext for identical plaintext, the database becomes vulnerable to . class User &lt

Note: This key should be a 32-byte hex string (or compatible with your key generator).
