Richard> Do you currently use any encryption on your local Org-files in Em= acs?=C2=A0 I've been meaning to examine AutoEncryption or CryptPlusPlus (ht= tp:// Richard> www.emacswiki.org/emacs/CategoryCryptography) to see how it plays= with Org.=C2=A0 If it worked well, my rough plan was to make MobileOrg abl= e to en/ Richard> decrypt files along those lines. Richard> If anyone has any better ideas, let me know.=C2=A0 I'm not sure h= ow this would best be implemented. I think there are two use cases for this problem.=20 * 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. --dmg Richard> -Richard Richard> On Tue, Dec 29, 2009 at 4:04 AM, D M German wrote: Hi everybody, =20=20=20 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? =20=20=20 thanks a lot! -- -- Daniel M.
