Import/Export allows new content and updates to existing content to be deployed from one Drupal database to another repeatedly while keeping track of IDs on the source and destination systems.
This module uses the jCryption plugin (http://www.jcryption.org version 1.2 only) to encrypt any form submission in Drupal using 265-bit public/private key encryption. For example, you can use it to encrypt the login and registration form, so a user's passwords are never transmitted in clear text. This is similar to how SSL works to encrypt traffic.
