RSA-250 has been factored. This computation was performed with the Number Field Sieve algorithm, using the open-source CADO-NFS software. The total computation time was roughly 2700 core-years, using Intel Xeon Gold 6130 CPUs as a reference (2.1GHz): RSA-250 sieving: 2450 physical core-years RSA-250 matrix: 250 physical core-years The computation involved tens of thousands of machines … Read More “RSA-250 Factored” »
