Class EncryptedBinaryType

Object
  extended by org.jasypt.hibernate.type.EncryptedBinaryType
All Implemented Interfaces:
org.hibernate.usertype.ParameterizedType, org.hibernate.usertype.UserType

public final class EncryptedBinaryType
extends Object
implements org.hibernate.usertype.UserType, org.hibernate.usertype.ParameterizedType

A Hibernate 3 UserType implementation which allows transparent encryption of byte[] values during persistence of entities.

This class is intended only for declarative use from a Hibernate mapping file. Do not use it directly from your .java files (although of course you can use it when mapping entities using annotations).

To use this Hibernate type in one of your Hibernate mappings, you can add it like this:

  <hibernate-mapping package="myapp">
    ...
    <typedef name="encryptedBinary" class="org.jasypt.hibernate.type.EncryptedBinaryType">
      <param name="encryptorRegisteredName">myHibernateByteEncryptor</param>
    </typedef>
    ...
    <class name="UserData" table="USER_DATA">
      ...
      <property name="resume" column="RESUME" type="encryptedBinary" />
      ...
    <class>
    ...
  <hibernate-mapping>
 

...where a HibernatePBEByteEncryptor object should have been previously registered to be used from Hibernate with name myHibernateByteEncryptor (see HibernatePBEByteEncryptor and HibernatePBEEncryptorRegistry).

Or, if you prefer to avoid registration of encryptors, you can configure your encryptor directly in the mapping file (although not recommended), like this:

  <hibernate-mapping package="myapp">
    ...
    <typedef name="encryptedBinary" class="org.jasypt.hibernate.type.EncryptedBinaryType">
      <param name="algorithm">PBEWithMD5AndTripleDES</param>
      <param name="password">XXXXX</param>
      <param name="keyObtentionIterations">1000</param>
    </typedef>
    ...
    <class name="UserData" table="USER_DATA">
      ...
      <property name="resume" column="RESUME" type="encryptedBinary" />
      ...
    <class>
    ...
  <hibernate-mapping>
