Limitation

• It takes time to download and decrypt whole file and show. (Except for videos)
• For video, it uses real-time streaming. Still, buffering can take time up to 1 minute.
• With private TLS certificate, you cannot use streaming in Chrome. Streaming is disabled for all WebKit browsers due to its limitation.
• Uploading with browser limits file size to 2GiB. Use python client to large-scale upload.
• Python client requires USAG-Lib and OpenCV dependency.
