The tests pass on my machine. What errors are you getting?

Are you using macOS or Linux?
I can't decrypt back to what to I encrypt. I run on macOS 10.12.

I'm running Linux 4.8. Decryption doesn't work for me using those specific keys, but with other keys it works fine. The crypto-numbers library's prime generation is probabilistic, so could it just be a rare case of it not working as it should, or does the problem recur on every test?
