DTU_4GLAN_HAL/app/IEC_SERVER/lib60870-C/tests/certs

This folder include test certificates for TLS related tests

• Three different root CAs ** root_CA1 ** root_CA2 ** root_CA3

• For each root CAs there are two clients and two server keys/certificates ** server_CA1_1 ** server_CA1_2 ** client_CA1_1 ** client_CA1_2 ** server_CA2_1 ** server_CA2_2 ** client_CA2_1 ** client_CA2_2 ** server_CA3_1 ** server_CA3_2 ** client_CA3_1 ** client_CA3_2

Example: Generate root CA keys and certificates:

openssl genrsa -out root_CA1.key 2048 openssl req -x509 -new -nodes -key root_CA1.key -sha256 -days 3650 -out root_CA1.pem

Example: Create endpoint (client/server) certificates:

openssl genrsa -out server_CA1_2.key 2048

openssl req -new -key server_CA1_1.key -out server_CA1_1.csr

openssl x509 -req -in server_CA1_1.csr -CA root_CA1.pem -CAkey root_CA1.key -CAcreateserial -out server_CA1_1.pem
