256 bit AES with a 128 character key would currently take ~5.26 X 10195 YEARS to try every possible key using the fastest supercomputer we currently have available to us today, . . Even if Google’s super Quantum computer were somehow 100 trillion times faster than that current super computer, it would then only take them ~5.26 X 10181 years to crack it. . . Thats quite a time savings that would still mean nothing to us since its been calculated that the Universe will devolve into a soup of quarks and other subatomic particles at a few fractions of a degree above absolute zero by ~4.2 X 1080 Years from now . . .
This reporter has literally no grasp of the law of very large numbers. I wonder where they would store the results of all this quantum calculating they propose to do? The sheer number of possible keys could exceed the number of atoms in the Universe on which to put the quantum calculation results on. . . They also seem to think that in 2022 the US military and other people interested in keeping secrets would not have moved on to Quantum encryption. . .
