 ## How It Works
 
 We use [this approach](https://paragonie.com/blog/2017/05/building-searchable-encrypted-databases-with-php-and-sql) by Scott Arciszewski. To summarize, we compute a keyed hash of the sensitive data and store it in a column. To query, we apply the keyed hash function to the value we’re searching and then perform a database search. This results in performant queries for exact matches. `LIKE` queries are not possible, but you can index expressions.

 ## Getting Started
 
-> Note: Your model should already be set up with Lockbox or attr_encrypted. The examples are for a `User` model with `encrypts :email` or `attr_encrypted :email`. See the [full example](https://ankane.org/securing-user-emails-in-rails) if needed.
