they have backdoors into any commercial encryption software plus the computing power to break most others.

If software backdoors to your encryption programs concern you (and it should IMO), you should use one of the free alternatives that are fully open source, like GPG.

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.
