サブジェクト代替名を使用した証明書の作成

SAN（サブジェクト代替名）を含める必要があるCA証明書を作成します。

openssl genrsa -des3 -out ca.key 2048
openssl req -new -x509 -days 3650 -key ca.key -out ca.crt -config ca_server.cnf

ca_server.cnf ファイルの内容:

[ req ]
default_bits       = 2048
distinguished_name = req_distinguished_name
req_extensions     = req_ext
prompt = no
[ req_distinguished_name ]
countryName                 =LT
stateOrProvinceName         = Some-State
localityName               = London
organizationName           = KKK
commonName                 = 192.168.1.8
[ req_ext ]
subjectAltName = @alt_names
[alt_names]
DNS.1   = 192.168.1.8

次のコマンドを使用して証明書の内容を確認してください。

openssl x509 -in server.crt -text

出力を取得します。
