Revoke a transfer

After you have performed a transfer, there may be reasons to revoke access to the files of this transfer for all recipients. The reason could be:

  • the containing information is outdated and obsoleted by a new transfer.

  • the transfer has been sent to the wrong recipient.

  • it is required to revoke access for all recipients due to security or regulatory reasons.

The transfer can be revoked by the sender, either by clicking Revoke in the Cryptshare Web App, or by clicking Revoke in the transfer status.

All files, including the message, will then be deleted from the Cryptshare Server, not available for download.

In order to revoke a transfer some time after sending, the user has to enable the option 'Send me a notification email about this upload' on the 'transfer options' page. After sending the transfer, the sender receives a sender notification mail, where he is able to use the 'Revoke' button. When using the button in the sender notification mail, it may be necessary for the sender to re-verify themselves in order to prove that they are in fact the original sender.
