----------------------------------------------

             Summary: Encrypted schema
                 Key: SYNCOPE-270
                 URL: https://issues.apache.org/jira/browse/SYNCOPE-270
             Project: Syncope
          Issue Type: New Feature
            Reporter: Francesco Chicchiriccò
             Fix For: 1.2.0


1. Main purpose: store some arbitrary string values encrypted in the database; this can be enforced by law, for example.

2. When defining an encrypted schema, you must provide the cypher  algorithm to be used and a passphrase.
Such passphrase will be stored by Syncope as encrypted with an internal key (more or less like we are already doing with user passwords).

3. When creating an attribute with such schema, the value(s) will be automatically encrypted by Syncope using the provided algorithm and passphrase.

4. When reading an attribute with such schema (e.g. contained in an AttributeTO), the value(s) will be sent encrypted.
Only who knows the algorithm and the passphrase will be able to decrypt.
Moreover, you can think to make the admin console able to show such attribute value(s) as encrypted by default and to decrypt them on demand after asking for algorithm and passphase.

5. When propagating / synchronizing attribute with such schema, GuardedString will be used, not String.

6. When changing algorithm or passpshase of an existing schema, new values will be encrypted with these, old values will remain as they are. 
Naturally, one can provide an update procedure.
