Hi, we are looking to use spring to integrate with certain external systems using socket connections. We will need to store the user names & passwords in a DB (Oracle 11g). Passwords will have to be encrypted in DB and spring needs to decrypt it and connect with the external systems with that parameter.

Can some one suggest ways to do it? Should we follow some encyption standards in DB and what decryption standards can spring decrypt?

Regards,
Srini
