As for breaking good encryption, good luck. Unless they have made a fundamental and previously unknown breakthrough in the mathematics involved, modern encryption, properly implemented is not crackable. Computational speed doesn't matter when the brute force attack on a key requires more power than exists in the universe. A 4k key should be safe until the heat death of the universe. That's long enough IMO.

I’ve watched a guy from China sit down and break a AES256 encrypted message with a desktop computer.
Until you get quantum computation, which breaks those rules.
