How to Generate CRS for SSL Certificate
To create CRS paste your customized OpenSSL CSR command into your terminal.
openssl req -new -newkey rsa:2048 -nodes -out STAR_linuxits_com.csr -keyout STAR_linuxits_com.key -subj "/C=BD/ST=Dhaka/L=Dhaka/O=LinuxITs Ltd/OU=LinuxITs/CN=*.linuxits.com"
- C=BD = Country Name (2 letter code) [XX]:BD
- ST=Dhaka = State or Province Name (full name) [ ]:Dhaka
- L=Dhaka = Locality Name (eg, city) [Default City]:Dhaka
- O=LinuxITs Ltd = Organization Name (eg, company) [Default Company Ltd]:LinuxITs Ltd
- OU=LinuxITs = Organizational Unit Name (eg, section) [ ]:LinuxITs
- CN=linuxits.com = Common Name (eg, your name or your server's hostname) []:linuxits.com
- CN=*.linuxits.com = Common Name (eg, your name or your server's hostname) []:*.linuxits.com
Common Name (Server Name) The fully qualified domain name that clients will use to reach your server. For example, to secure https://www.example.com, your common name must be www.example.com or *.example.com for a wildcard certificate.
