A wildcard certificate for *.example.com can secure any-subdomain.example.com. The asterisk (*), or star, is the wildcard and can be any valid subdomain. About the Common Name (CN) Every SSL certificate has a Common Name, or CN for short. When generating a Certificate Signing Request , the CN can

In case you need a higher trust level than domain-validated, wildcard certificates are still an option. Also from 2017, note the comment below, by @ha9u63ar: According RFC 2818 sec. 3 using CN for host name identification is not recommended anymore (deprecated) Subject Alternative Name (SAN) seems to be the way to go. Next, run the following command to generate the CSR and the private key files: openssl req -newkey rsa:2048 -nodes -keyout yourdomain.key -out yourdomain.csr. Here yourdomain.csr stands for your CSR file and yourdomain.key stands for the private key file.!!ATTENTION!! Do not delete the private key! 2. Enter CSR and Private Key command. Generate a private key and CSR by running the following command: Here is the plain text version to copy and paste into your terminal: openssl req -new -newkey rsa:2048 -nodes -keyout server.key -out server.csr. Note: Replace “server ” with the domain name you intend to secure. 3. Enter your CSR details OpenSSL: Convert DER to PEM. openssl x509 -in cert.der -out cert.pem. You can also use similar commands to convert PEM files to these different types of files as well. Furthermore, there are additional parameters you can specify in your command — such as -inform and -outform — but the above examples are the basic, bare bones OpenSSL commands.
