Encryption

Crossposted to security group and France group, my apologies for not being able to write this in French. Comments are welcome in French or English, of course.

There are some new French laws on user information and how it is handled which seem to have implications for security.

Hacker News has a thread about this that talks about the actual requirements which seem to be compatible with the way Drupal core works.

Hey SDUG, Sandcamp seems like an ethereal memory....Anyway, we have an ecommerce project where the client would like to collect sensitive information, like insurance and social security number data. We would like to encrypt this info. A few questions:

1.http://drupalmodules.com/node/2461 -- This is the client-side encryption module -- is this the right module for that type of issue?
2. Anyone actually use/try this? Will this type of thing stop your average hacker?
3. Any other suggestions?
