   * Encryption is performed using PostgresSQL's native [PGP functions](http://www.postgresql.org/docs/9.1/static/pgcrypto.html).
   * It requires the `pgcrypto` PostgresSQL extension:
     `CREATE EXTENSION IF NOT EXISTS pgcrypto`
   * ActiveRecord logs are [automatically](https://github.com/jmazzi/crypt_keeper/blob/master/lib/crypt_keeper/log_subscriber/postgres_pgp.rb)
     filtered for you to protect senitive data from being logged.
+  * Custom options can be set through the `:pgcrypto_options`. E.g. `crypt_keeper :field, encryptor: :postgres_pgp, pgcrypto_options: 'compress-level=9'
