Is it possible to organize the signing of the user's digital signature files using the WEBDAV protocol?

Question

webdav

All good!
Is it possible (worth it :)) to think in the direction, organize the transfer of files using the WEBDAV protocol and implement the signature of these files with the user's EDS?
Or it is worth leaning towards the file signing algorithm, through the browser, using the CryptoPro plugin.
Maybe someone thought in this direction....
