you can add it to your entity mapping as described in this tutorial ( http://www.thoughts-on-java.org/how-to-use-jpa-type-converter-to/ )

<entity-mappings version="2.1"
    xmlns="http://xmlns.jcp.org/xml/ns/persistence/orm"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/persistence/orm_2_1.xsd">

    <entity class="x.y.Entity">
        <convert converter="x.y.CryptoConverter" attribute-name="yourField"/>
    </entity>
</entity-mappings>
