NINA is a unique provider hosted application that allows end users to encrypt their sensitive files stored in SharePoint server / SharePoint Online. Encryption can either be triggered manually by the user using one of the ribbon buttons, or automatically by Nintex workflow.
Let's say, the document goes through an approval process, when the approval is done, the final action of the workflow is the http request, which calls the provider hosted application NINA and returns the enrypted file to the SharePoint document library.
Furthermore, generation of the one time url for download of the encrypted file is supported (one time passoword for decryption is sent via text message to the user's mobile phone). It is a great way how to securely distribute content to external users, who can download the file from the generated one time url.
