o Generate the private key as below.
   $ openssl genpkey -algorithm X25519 -out /etc/open5gs/hnet/curve25519-1.key
   $ openssl ecparam -name prime256v1 -genkey -conv_form compressed -out /etc/open5gs/hnet/secp256r1-2.key

 o The private and public keys can be viewed with the command.
   The public key is used when creating the SIM.
   $ openssl pkey -in /etc/open5gs/hnet/curve25519-1.key -text
   $ openssl ec -in /etc/open5gs/hnet/secp256r1-2.key -conv_form compressed -text
