Getting Private key

Generally speaking, it only takes three steps: 1. Openssl genrsa-out server.key 20482. Openssl req-new-key server.key-out server.csr3. Openssl x509-req-days 365-in server.csr-signkey server.key-out server.crt about the password: openssl genrsa-out server.key 2048 does not need a password. Openssl genrsa-des3-out server.key 2048 requires a password. Https://www.jianshu.com/p/9523d888cf77 about domain name: use openssl, domain name can not be lost; with keystore, you must enter.
