Rymdport (formerly wormhole-gui) is a cross-platform application that lets you easily and safely share files, folders, and text between devices. The data is sent securely with end-to-end encryption using the same protocol as magic-wormhole. This means that Rymdport can talk not only to itself, but also to other wormhole clients.
      The transfers are implemented using wormhole-william, a native Go implementation of magic-wormhole. As a result, Rymdport compiles into a native binary with no runtime dependencies while also outperforming the reference implementation of magic-wormhole.
