The article says that DES "can be brute forced in a single digit number of days by a modern computer".
2**56 keys / 9 days ≈ 92.7 Gkeys/s
Can modern computers actually compute DES that fast?
- mikeash 9y agoHere's a project that did 1.4G/s on a single GPU five years ago: https://www.reddit.com/r/crypto/comments/162ufx/research_project_opencl_bitslice_des_bruteforce/ https://www.reddit.com/r/crypto/comments/162ufx/research_pro... Stick multiple modern GPUs in a machine and single digit days seems feasible.
- danbruc 9y agoThis benchmark [1] gives 196.2 GH/s for DES using 8 Nvidia GTX 1080 Ti and Hashcat 3.5. So while your average computer is probably not quite sufficient it is certainly in reach.
