The EU wants to spend your money to assemble a giant mass surveillance machine with little effect on harm against children. Chat Control is not effective, weakens security for all and does not respect privacy. Contact your EU representatives and let them know.

More than 500 researchers have signed an open letter against the dangerous EU proposal on chat control.
The proposal remains ineffective, undoes decades of results in E2E encryption, and threatens the privacy of half a billion citizens.

Really cool post on DH!
"Finite field Diffie-Hellman is also just Elliptic Curve Diffie-Hellman, just over a curve that accidentally twisted itself a bit."

There is no Diffie-Hellman but Elliptic Curve Diffie-Hellman
When I first learned about Diffie-Hellman and especially elliptic curve Diffie-Hellman, I had one rather obvious question: Why elliptic curves? Why use this strange group that seems rather arbitrar…
