WebDAVBlackbox package of SecureBlackbox®

SecureBlackbox product diagram

With WebDAVBlackbox you can connect to existing servers using WebDAV protocol and also build your own WebDAV servers.

WebDAV protocol lets you create, change, copy and move documents on the server (usually a web server but you can run a separate WebDAV server) and create and manage collections (directories) of documents.

WebDAVBlackbox also includes client- and server-side components for CardDAV Extension to WebDAV.

The benefit of WebDAV is that it offers a way to access and manage remote files and directories via HTTP/HTTPS (technically WebDAV protocol is an extension to HTTP/HTTPS). Due to this HTTPBlackbox package is included in WebDAVBlackbox.

Since HTTPS is built on top of SSL/TLS connection, WebDAVBlackbox includes components for generic SSL/TLS transport.

For certificate creation, management and validation WebDAVBlackbox uses PKIBlackbox, base functions of which are included with HTTPBlackbox package.
