> 1. On the second tab of the Clinical Group form (Study Export), make sure you have entered a Study Participant ID to enable the Generate Keys button.
> 2. Click Generate Keys to create a public/private 1024-bit encryption key pair.
> 3. Do one of the following:
> - Click Save Public Key to Disk to generate a text file that you can use to share the public key with whoever will be importing your data.
> - Highlight the public key, copy it, and then paste it into an e-mail message or other word processing program for sharing.
> 4. Click OK to save the keys in the Clinical Group form.
> If you try to modify previously created keys you will be warned before saving the record since an inadvertent change will destroy the utility of the paired keys.Related topics
