Using genkey.sh on google iot core example does not work

[netskink]

Using the genkey.sh script to create a key does not work. The generated .pem file will fail when you try to add to the Google Cloud console IOT Core Registry CA certificate will say "Certificate is in an invalid PEM format."

What are th.e steps to reproduce this issue?

1. Recreate the file system for the pycom-libraries/GoogleIOT example
2. Cd to pycom-libraries/GoogleIOT/
3. ./genkey.sh some-name
4. In google cloud console navigate to hamburger menu on upper left->BigData->Iot Core->my registry
5. Click registry entry name for details
6. Click CA Certificates
7. Click Add certificates
8. Click upload
9. Browse to db/ and select the public .pem file.
10. click ok

Also tried to modify flash/config.example.py to have valid project id and did above. It had same result.

What happens?

The generated .pem file will fail when you try to add to the Google Cloud console IOT Core Registry CA certificate will say "Certificate is in an invalid PEM format."

What were you expecting to happen?

I was expecting the CA certificate to be added.

Any logs, error output, etc?

Any other comments?

I had a similar problem using the official google repo version of this file. I was able to get a cert to upload there. Here is the issue.
GoogleCloudPlatform/iot-core-micropython#10
