How do I use nCrypted Cloud?

Encrypt an existing folder

nCrypted Cloud does not automatically encrypt all of your files by default. You need to choose the data you wish to protect.

  1. Right click on the folder you wish to encrypt and click Make Private.
  2. Click Yes on the confirmation box.


You can confirm that the folder has been encrypted by looking for the padlock symbol. The briefcase symbol shows that the folder has been encrypted with your Imperial College London identity, meaning that we can recover it in the event of an emergency.

Encrypt a new folder

  1. Right click on a space and select New > Folder. nCrypted Cloud will prompt you to encrypt the new folder by default.
  2. Click Yes.

Share and collaborate securely

To share data with collaborators, follow these steps:

  1. Right click on the folder you wish to share, select nCrypted Cloud and click Share Securely.
  2. Share the folder from within Dropbox by right clicking on the folder and selecting Share Dropbox link.
  3. Email the link that has been copied to your clipboard.

If you are sharing the folder with somebody external to Imperial College London, he or she will need to download and install nCrypted Cloud to read the files. Personal accounts are free so he or she will not be charged for this service.

See who has access to your files

By default, nCrypted Cloud relies on Dropbox share permissions to restrict access to read your files. A further restriction of enforcing work identity is in place, meaning that you can only share your data with other members of Imperial College London. This restriction can be lifted on a per folder basis to enable you to give access to external collaborators. Alternatively, you can limit who accesses your folders to allow only named individuals access.

To see who has access to your files, follow these steps:

  1. Right click on the folder and select Shared With.
  2. Read who has access to that file in the screen that appears.

Share a file temporarily

If you wish to share a file temporarily, you can do so with Trusted Sharing. With Trusted Sharing you have the following features:

  • Expiry
  • Password protection (security code)
  • Permissions (read only, download or both)
  • Watermarking.

To use Trusted Sharing, you need to link your nCrypted Cloud account to your Dropbox account. To do so, follow these steps:

  1. Right click on the file you wish to share within the nCrypted Cloud application and click Trusted Sharing.
  2. Set your preferences in the new screen and click OK.
