[jasypt-users] Jasypt + Hibernate3 integration + decrypt

[jmiranda <jm...@gm...>]

Hi!

I would like to encrypt some attributes of an entity in a transparent way
when I persist it into database using Hibernate. I've followed the guide:
http://www.jasypt.org/hibernate3.html and it works like a charm.

The problem is that when I want to get back the entity from database I would
like to get the entity with all attributes decryted. I don't know if I am
missing something important but I get the attributes encrypted.

I've followed all the steps of the guide. Any ideas?.

Thanks in advance.

Solved.

Everything works well doing some executions, I initialize Spring container
(is a web app) 5 or 6 times and then... 

Caused by: org.jasypt.exceptions.EncryptionInitializationException: No
string encryptor registered for hibernate with name
"strongHibernateStringEncryptor"
	at
org.jasypt.hibernate.type.AbstractEncryptedAsStringType.checkInitialization(AbstractEncryptedAsStringType.java:250)
	at
org.jasypt.hibernate.type.AbstractEncryptedAsStringType.nullSafeGet(AbstractEncryptedAsStringType.java:142)
	at org.hibernate.type.CustomType.nullSafeGet(CustomType.java:105)
	at org.hibernate.type.AbstractType.hydrate(AbstractType.java:81)

Any ideas?.

You need to make an entry of strongHibernateStringEncryptor in your spring
context i.e. applicationConext.xml in my case.

Something like this.

<bean id="strongHibernateStringEncryptor"
	    class="org.jasypt.encryption.pbe.StandardPBEStringEncryptor">
	    <property name="algorithm">
	        <value>PBEWithMD5AndTripleDES</value>
	    </property>
	    <property name="password">
	        <value>jasypt</value>
	    </property>
	</bean>

Hope this helps.

Leo.

Hi Leo, yes I had this piece of configuration.  Maybe I was missing
something. At the end I've created a spring bean and inside I've used jasypt
to encrypt/decrypt, then I have to get the bean and call decrypt/encrypt
everytime I want to get/update my entity but doesn't matter, is just in one
time and it does not supose a big headchache :)

Thanks for your help.

Re: [jasypt-users] Jasypt + Hibernate3 integration + decrypt

[Allan L. <lan...@gm...>]

I've also recently hit the "No string encryptor registered for hibernate..."
error and I'm also using Spring. The solution I found to the intermittent
initialisation problem was to make my data access components dependent on
the strongHibernateStringEncryptor bean, thereby ensuring that bean was
always present in the application context before any of my data access
components might start to try doing anything requiring en/decryption. I
think I hit the problem because another of the beans in my Spring definition
performed some data access as part of the execution of its init-method, and
I guess there is no guarantee that this is called after all other beans have
been instantiated.

So anyway, long explanation, but simple solution. Try adding something like
this, shown here on another bean which forms part of my data access
infrastructure:

	<bean id="transactionManager"
		class="org.springframework.orm.hibernate3.HibernateTransactionManager"
		depends-on="hibernateStringEncryptor">
		<property name="sessionFactory" ref="sessionFactory" />
		...
	</bean>

	<bean id="hibernateStringEncryptor"
class="org.jasypt.hibernate.encryptor.HibernatePBEStringEncryptor">
		<property name="registeredName" value="strongHibernateStringEncryptor"/>
		<property name="password" value="..." />
	</bean>

Hope that helps.
