Re: [Orgmode] Encrypting files for org-mobile

Hi Richard,

 I've been meaning to examine AutoEncryption or CryptPlusPlus (http://

with Org.  If it worked well, my rough plan was to make MobileOrg able to en/

would best be implemented.

I think there are two use cases for this problem. 

* On one side is the people who work with encrypted files. the
  mobile-org application would need to be aware of the type of
  encryption used. I suspect many people would be willing to change
  encryption method to the one used in org if it was "good enough".

* On the other there is the people who are only interested in encrypting
  the files in the server to avoid them to be browsed by unwanted
  eyes. I suspect that even a simple symmetric encryption method will be
  sufficient here for the majority of the users.

these two uses cases are not mutually exclusive. One can imagine an
scenario where only one or more files are encrypted at the client level,
but the user wants all the files uploaded to the server to be made
available in encrypted mode at the file system level on the server.

Which get me thinking... is there a way to decrypt the files on the file
at the server as they are requested by the mobile-org client? In other
words, the files are encrypted in the server, but when the user requests
them (and provides the proper credentials---such as in the current
environment) the files are then decrypted on the file before they are
sent to the iphone. I suspect this is probably implemented somehow.

I have an iphone development environment (no dev. license though) and I
learning objective-C. I am not very good at UI, but I can help with the
backend code, if necessary.

    Hi everybody,
   
    Does anybody know if it is possible to keep the files for org-mobile
    encrypted in the server? I know you can protect them with a password,
    but that protection is from people who look into the server. How about
    protecting it from the people who run the server?
   
    thanks a lot!
