CA 인증서를 사용하여 클라이언트 인증서 생성

를 사용하여 클라이언트 인증서를 생성하려면 AWS CLI

1. 키 페어를 생성합니다.

   openssl genrsa -out device_cert_key_filename.key 2048

2. 클라이언트 인증서에 대한 CSR을 생성합니다.

   openssl req -new \
       -key device_cert_key_filename.key \
       -out device_cert_csr_filename.csr

   아래와 같이 몇 가지 정보를 입력하라는 메시지가 표시됩니다.

   You are about to be asked to enter information that will be incorporated
   into your certificate request.
   What you are about to enter is what is called a Distinguished Name or a DN.

3. CSR에서 클라이언트 인증서를 생성합니다.

   openssl x509 -req \
       -in device_cert_csr_filename.csr \
       -CA root_CA_cert_filename.pem \
       -CAkey root_CA_key_filename.key \
       -CAcreateserial \
       -out device_cert_filename.pem \
       -days 500 -sha256
