A 30-qubit quantum computer would equal the processing power of a conventional computer that could run at 10 teraflops (trillions of floating-point operations per second).

The Mathematics Behind Quantum Computing: Part I
(May 2007)
For a 1024-bit number, Shor‘s Algorithm requires on the order of 1024(3), about one billion, operations. I do not have any information on how quickly quantum operations can be executed, but if each one took one second our factorization would last 34 years. If a quantum computer could run at the speed of today‘s electronic computers (100 million instructions per second and up) then factorization of the 1024-bit number would be a matter of seconds.

TLS 1.3: Slow adoption of stronger web encryption is empowering the bad guys
(April 6, 2020)
Asymmetric encryption is used during the “handshake”, which takes place prior to any data being sent. The handshake determines which cipher suite to use for the session – in other words, the symmetric encryption type – so that both browser and server agree. The TLS 1.2 protocol took multiple round trips between client and server, while TLS 1.3 is a much smoother process that requires only one trip. This latency saving shaves milliseconds off each connection.

SERVER DOES NOT SUPPORT TLSv1.3
Consider enabling support of TLSv1.3 protocol that is considered to be the most secure and stable version of TLS protocol.
Europe’s Moral Crusader Lays Down the Law on Encryption
Arrayed against her is a fierce coalition of privacy advocates, American YouTubers, German soccer fans, and tech executives who argue that the proposal would severely impact online privacy. They call it the “chat control” bill and warn that it would open dangerous backdoors into encrypted apps. Because Johansson has made herself the face of this bill, criticism is lobbed at her personally. “Either she’s stupid or she’s evil,” says Jan Jonsson, CEO of Swedish VPN service Mullvad. In February, she was given a dubious “prize” at the Dutch Big Brother Awards, an event organized by digital rights group Bits of Freedom, which identifies heroes and villains in the fight for privacy.
Biden said Zelenskyy gave ‘flat assurance’ he won‘t use F-16s in Russia: Ukraine live updates
Biden told Group of Seven leaders Friday the U.S. would assist with training Ukrainian pilots on modern fighter aircraft, including American-made F-16s, in a possible signal that Washington is closer to arming Ukraine with the planes.
G7 calls for developing global technical standards for AI
The agreement came after the European Union, which participates in the G7, inched closer this month to passing legislation to regulate AI technology, potentially the world‘s first comprehensive AI law that could form a precedent among the advanced economies.
„We want AI systems to be accurate, reliable, safe and non-discriminatory, regardless of their origin,“ European Commission President Ursula von der Leyen said on Friday.

Eine solche Ausweitung der von der EU-Kommission geplanten „Aufdeckungsanordnungen“ für Provider auch auf gesprochene Kommunikation dürfte sehr weitreichende Folgen haben. So könnten etwa neben Sprachnachrichten über Messenger-Dienste auch auf Online-Anrufbeantwortern hinterlassene Botschaften oder Telefonanrufe umfasst sein.
