Charles Spencer, brother of the late Princess Diana, has released a new book in which he remembers his sister as an unforgettable figure. The memoir offers personal reflections on Diana's life and their family relationship, and coverage of its publication is drawing attention from readers interested in her legacy.

A new cryptography paper describes a method for forging 1024-bit RSA digital signatures in time close to the Special Number Field Sieve, one of the fastest known factoring approaches. The work suggests 1024-bit RSA keys, still used in some older systems, offer less security margin than previously assumed. Security researchers are weighing what this means for legacy infrastructure and how soon key sizes should be raised.
