This is a proof of concept to test client-side encryption of genomic data. It requires a modern version of a chromium-based browser (e.g. Google Chrome/Microsoft Edge).
No data is transferred from your computer. All work happens on your local computer, in the web browser.
The sender's key (you) will be randomly generated.
Check the developer console (F12) to see if encryption has finished.
A 300MB file takes about 10 seconds to encrypt. A 1GB file will take about 30 seconds to encrypt.
Files larger than this probably won't work currently.
