@hntooter Boost with CW: Wha?? Software patents, Signal/Matrix.

@IceWolf Could you add a link because since .social is muted the original post isn't visible (for anyone who doesn't happen to follow them already)

@IceWolf @hntooter It seems the original Signal's Double-Ratchet was not covered, rather, the patent was claiming a generalized Double-Ratchet based on the existing work of Signal (and mentioned post-quantum Diffie-Hellman for once).

But it still looks dodgy. To what extent the claims apply to a possible variant of Double-Ratchet that may be used in the future? Only patent lawyers know...
