Generate server certificate/key pair-

openssl ecparam -out server_key.pem -name prime192v1 -genkey

openssl req -new -key server_key.pem -days 6500 -set_serial 2222 -subj

“/C=IT/ST=Lombardia/L=Milan/O=STM/OU=R&D/CN=server domain” -out

server_cert_req.pem

openssl ca -in server_cert_req.pem -out server_cert.pem -days 6500 -keyfile

ca_key.pem -cert ca_cert.pem -notext -batch

Generate client certificate/key pair:

openssl ecparam -out client_key.pem -name prime192v1 -genkey

openssl req -new -key client_key.pem -days 6500 -set_serial 3333 -subj

“/C=IT/ST=Lombardia/L=Milan/O=STM/OU=R&D/CN=client domain” -out

client_cert_req.pem

openssl ca -in client_cert_req.pem -out client_cert.pem -days 6500 -keyfile
