[Applies to the latest release, Boxcryptor_v2.0.435.407_Setup.msi].
I am having problems similar to those reported to the Support Desk by Andy [Permissions, Andy, Jun 04, 2014 04:09PM CEST] when trying to share an encrypted folder over OneDrive. Suppose I am user A, and my colleague is user B. I am running the above version of Boxcryptor on Windows 8.1 Pro, linked to OneDrive. User B is running the same version on Windows 7 Ultimate, also linked to OneDrive. Both of us have checked carefully that the EFS service is disabled, and I have set OneDrive so that all files are always available offline, i.e. standard OneDrive usage.
I have done the following:
1) Created a folder called Experiment under OneDrive in the BoxCryptor drive (X:), and copied two Word documents and two text files into it.
2) Encrypted Experiment and its contents, resulting in an encrypted folder and files in the actual Experiment folder in OneDrive, then used Manage Permissions for Experiment in X: to grant access to the folder for User B. Then I checked that the permissions for each individual file in turn were also set to grant access for B.
3) Checked that the encrypted files were present in Experiment in OneDrive, together with FolderKey.bch, and noted the modification times so as to check syncing.
4) Manually triggered syncing to OneDrive at the appropriate times and when advised by BoxCryptor.
5) Checked over the web at OneDrive.com that the files were present and correct, with the correct timestamps.
6) Shared the Experiment folder from OneDrive on the web to User B's OneDrive account.
7) Now User B downloaded from this share a zipped copy of the Experiment folder including all five files, after checking the modification times etc. He unzipped this into his OneDrive folder on his PC, producing an Experiment folder like mine. (OneDrive does not provide the facility to sync shares back to the PC of the person to whom a folder has been shared).
8) Now the Experiment folder appeared in User B's BoxCryptor drive, and when he checked its permissions, he found that BoxCryptor agreed that he and I both had access to the folder. The filenames appeared in green, as expected.
9) However, when he checked each individual file, he found that he had not been granted access to any of them. According to BoxCryptor at his end, only User A (me) has access permission. Any attempt to open or decrypt the files leads to an access authorization error.
This exercise has been repeated several times on both computers, each time with the same result. I have been careful to ensure that syncing completed properly, as well as making sure that FolderKey.bch has been appropriately updated during the test encryption processes. Unless I have made an egregious mistake, this is looking like a bug in the BoxCryptor permissions server processes. Access is granted to the folder, but not to the files it contains.
Feel free to contact me for any more data you might want.
