Each user of an encrypted data room needs a file key for each file in the room to open the respective file. If a new file is uploaded to an encrypted data room, keys must therefore be generated for the file for each user in the room. If an encrypted data room has many users (due to large assigned groups, for example), a large number of file keys might need to be generated. The number increases accordingly if many new files are uploaded at once, for example.

Each user who already has a key for a particular file can generate file keys for other users and participate in the key distribution (this happens automatically in the background when the Web App is open or DRACOON for Windows/Mac is connected to a DRACOON drive). Therefore it is crucial that already at the beginning (immediately after the upload) as many users as possible receive a key for a new file because the further key distribution (to even more users) is thus exponentially accelerated (since everyone who has a key can participate in the key distribution).

Previously, only 2 file keys were generated by the DRACOON Web App immediately after a file was uploaded to save time—if the Web App was closed by the uploading user immediately afterward, no more file keys would be initially generated by the uploading user, and it was more likely that not all users in the room could access the new file from the beginning.

Summary: Due to the now significantly faster key generation, up to 50 file keys can now be generated after uploading a file without noticeable delay. The fact that an upload is now marked as complete only after the 50 file keys have been generated prevents the user from prematurely closing the web app before enough file keys have been generated. In addition, prioritizing the newest uploaded file during key generation ensures that sufficient file keys are initially available for each file.
