                                     Self signed certificate process

2. Common Method

• Key It's a private key openssl grid , Usually rsa Algorithm .
• Csr It's a certificate request file , Used to apply for a certificate .
• crt yes CA Certificate after certification , The signer uses his own key Here's your signed certificate .

• key Generation
  openssl genrsa -des3 -out server.key 2048
• Generate a without a password key
  openssl rsa -in server.key -out server.key
• To generate CA Of crt
  openssl req -new -x509 -key server.key -out ca.crt -days 3650
• Generate csr
  openssl req -new -key server.key -out server.csr
openssl x509 -req -days 3650 -in server.csr -CA ca.crt -CAkey server.key -CAcreateserial -out server.crt

• One step in place , Replace with your own domain name or IP Address ( Pay attention to the symbols , Reproducible address bar )
  openssl req -x509 \
-sha256 -days 3560 \
-nodes \
-newkey rsa:2048 \
-subj “/CN=xxxx/C=US/L=San Fransisco” \
-keyout domain.key -out domain.crt
