    So I've used live Mesh for quite awhile now and this version is finally getting really useful.  After I figured out how to get the paths all pointed to drive C:\MeshShareC the pointers in XML and such now all work between my computers.  This issue really effects any XML that points to another as mesh puts them in a place that doesn't match the pointers.

    So now I want to go up to the next step and encrypt a folder inside of my share.  This works fine on the computer but as mesh is running under my user context it decrypts it automatically and sends it to the other computers.

    When it sends it to the other computer it is unencrypted.  So on the other computer I turned encryption on for the folder/file and updated it.  Sure enough it's encryption got stripped on the other end.

    This seems like a bug to me.  If mesh supports the file system it should support the encryption.  Another issue I thought of is how it is on the wire, is anything in a file that is in plain text transmitted as such?

    This to me seems to imply that my data is not secured when it is transferred.  Mesh would be perfect for storing and transferring encrypted data if it supported the windows EFS type.

    I guess I could store the sensitive information on a bitlocker to go drive and mesh that file/folder but I would have to reserve the drive letters on all of my computers or the XML issues will rise again.

    Any help or direction would be appreciated.  Again the goal here is to have an encrypted XML file (InfoPath in Particular) that can be stored and meshed about several computers and require a password to access that file or folder.  Inside that file/folder sensitive information could be stored securely.

     

    Thank you,

    Steve what kind of encryption do you mean?  EFS?  I found this article on how EFS works, and in your case above, everything is working as designed.  Live Mesh is just like any other application, Word, Excel, etc. that if you opened a file in an encrypted EFS store, it would be decrypted upon open.  In this case, Live Mesh accesses the file in the same way Word or Excel does and then transfers that file to the other locations. 

    I can't say for sure, but I would also assume that the EFS private key is unique to each workstation where EFS is turned on...and unless you back up that EFS cert and install it on each of the other devices you wouldn't be able to read an EFS encrypted location.

    Someone please correct me if I'm wrong...my assumptions on EFS are based largely on my experience with it as a user not as an administrator.

    Hi,

     

    The files that are stored on the Microsoft servers “in the cloud” (the 5 GB of Live Desktop storage that each user gets) are protected by access controls but are not encrypted.

     

    Meanwhile, as this forum focuses on Windows 7 specific issues, this inquiry would best be posted to the corresponding forum:

    The reason why we recommend posting appropriately is you will get the most qualified pool of respondents, and other partners who read the forums regularly can either share their knowledge or learn from your interaction with us.  Thank you for your understanding.

     

    Regards,
