EMC VoyenceControl v4.1.0 Database Encryption, User Accounts Encryption

Hi,

Another set of novice questions that i cannnot find answers to in the documentation.

I need to determine the level of encryption of the VoyenceControl database and information content. Hence, can anyone assist with the following questions :

1. What is the encryption used within the VoyenceControl v4.1.0 database (Postgres) ?
   
2. What is the encryption used for local account password management if you are not using authentication services.
   
3. Is there any encryption used on the Application Server for the zipped backup files of data extracted from the Database system ?.
   

Again, this is preliminary design work.

Thanks in advance for any guidance and assistance.

Regards,

Richard.
