Setting up decryption

---

The third tab of the Clinical Group form allows you to set up decryption of shared data. On this tab:

The study coordinator can enter the names and Study Participant IDs of all those involved in the study, as well as enter or modify participants' public keys to allow decryption of their data.
Participants can enter the coordinator's public key to enable them to decrypt study tools or other data sent from the central collection site.

Study participants should generate their own key pair and send the public (decryption) key to the study coordinator. The coordinator can then import the participant's public key using the following procedure.

To add Study Participant IDs and public decryption keys

On the third tab of the Clinical Group form, click Add Participant to begin the process of entering the participant's name, ID number and public key

.
Enter the ID and click OK.
Click Modify Participant Info.
Enter a name in the dialog and click OK.
Click Modify Public Key and confirm that you want to modify the public key for this participant.
Click OK.
Copy the public key that this participant has sent to you, paste it into the Public Key dialog, and click OK


The Key Status column at right will show the italicized word "Yes" to indicate that you have stored the participants's key.

Clicking Save Public Key to Disk allows you to create a text file with the selected participant's public key. The file can then be distributed on disk or opened in a word processing program for copying and pasting. You can also remove a participant from the list by clicking Delete Participant ID.

Generate Key button

Selecting this button will generate a public/private 1024-bit key pair for encryption purposes. The keys are in a special "text" format that can be copied and pasted in a document or e-mail. Any modifications of previously created keys will result in a warning to the user before saving the record since an inadvertent change will destroy the utility of the paired keys.
