What is known about how Eric Lu factored the 862-bit RSA-260 after 35 years
What happened
862-bit RSA-260 fell on September 3, 2026 after 35 years. I verified the posted factor in Python on an M4 Mac mini, traced the viral 'seven months by hand' story to a joke, and sized the compute from RSA-250's 2,700 core-years with the GNFS formula.
