Creating a certificate

For devices to interact, you need X.509 certificates. If don't have one, you can create a certificate, for example, with OpenSSL:

$ openssl req -x509 \
-newkey rsa:4096 \
-keyout key.pem \
-out cert.pem \
-nodes \
-days 365 \
-subj '/CN=localhost'

Where:

-x509: X.509 certificate.
newkey: Encryption algorithm.
-keyout: File to write the private key to.
-out: File to save the certificate to.
-nodes: This flag is set when no public key encryption is required.
-days: Certificate validity period in days.
-subj: Request object.
