Hi ,
I am very new to this Hibernate great world. I need to Encrypt few fields of DB and need to decrypt same fields .
May I know the list of Algoriths which can I use in " name="algorithm">PBEWithMD5AndDES"

I am using below code for same :
--------------------------------------
?xml version="1.0"?>

<!DOCTYPE hibernate-mapping PUBLIC

"-//Hibernate/Hibernate Mapping DTD 3.0//EN"

"http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd">

<hibernate-mapping>
<typedef name="encryptedString" class="org.jasypt.hibernate.type.EncryptedStringType">
<param name="algorithm">PBEWithMD5AndDES</param>
<param name="password">thisisatest</param>
<param name="keyObtentionIterations">1000</param>
</typedef>
<class name="roseindia.tutorial.hibernate.Contact" table="CONTACT">
<id name="id" type="int" column="ID" >
<generator class="increment"/>
</id>
<property name="firstName" column="FIRSTNAME" type="encryptedString" />

</class>
------------------------------------------------------------------------
One thing I am clear that since I am using the PBEWithMD5AndDES as Algorith I cant decrypt the fields :(. Is there any Algorithem which can use in this place and Do the Encryption and Decryption.

AFAIU you need to save some passwords in DB, if so you can read about "hashing with salt" technique: http://www.google.ru/search?q=hash+salt+password
