使用您的 CA 证书创建客户端证书

要使用创建客户证书 AWS CLI

1. 生成密钥对。

   openssl genrsa -out device_cert_key_filename.key 2048

2. 为客户端证书创建 CSR。

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

   系统将提示您输入一些信息，如下所示：

   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.
   There are quite a few fields but you can leave some blank
   For some fields there will be a default value,
   If you enter '.', the field will be left blank.
   -----
   Country Name (2 letter code) [AU]:
       State or Province Name (full name) []:
       Locality Name (for example, city) []:
       Organization Name (for example, company) []:
       Organizational Unit Name (for example, section) []:
       Common Name (e.g. server FQDN or YOUR name) []:
       Email Address []:
   
       Please enter the following 'extra' attributes
       to be sent with your certificate request
       A challenge password []:
       An optional company name []:

3. 从 CSR 创建客户端证书。

   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
