`np setup` fails to parse newly-generated keypair

[rokroskar]

Hello! 👋

I've tried creating a keypair a few different ways (openssl genrsa and using the pycryptodome library) - I can read the keys with pycryptodome but the np setup process fails with:

What are the requirements for the keys? Do you have some instructions on how to generate a keypair that works?

@rokroskar Looks like the following works:

np setup --newkeys

Also see np setup --help for more options.

Would be nice if this were mentioned in the setup instructions...

For reference, here's how the keys are created:
