Multi-user encrypted volumes
Posted on 2010-08-13
Can anybody recommed some software which will allow encrypted volumes with multiple passwords or some other solution to the scenario below?
The scenario is as follows:
- Managers each need their own encrypted area with their own password.
- IT Admins need to be able to backup the encrypted data but not be able to decrypt it.
- A company director needs to be able to access every person's data with his own password (as opposed to having all the users' passwords).
- Ideally there would be the flexibility to have shared areas which each manager has a separate password for.
This is for a fairly small amount of data, say 10 users with 1gb of storage each. It is in a windows server/xp desktop environment. The problem is IT Admins not being able to decrypt the data otherwise it would be pretty straightforward just using NTFS permissions and IT Admins then encrypting the backups.
We thought about using truecrypt with keyfiles but the only way to use it with multiple passwords is to use smart cards holding the keyfiles.
