RSA cryptosystem faces new classical attack, but widespread panic can wait

Eric Lu factored an 862-bit RSA key for $400K using GPUs, putting RSA-1024 cracking costs at $30M and accelerating post-quantum crypto timelines.

There’s a new way to break RSA that’s faster than anything we’ve seen before

The world has known for decades that the RSA cryptosystem’s days are numbered. Once quantum computing becomes practical (estimates for that range from 3 to 20 or more years), the foundational security ...
