Hey, here are a few steps to create your own CA-signed certificates with your own CA:<\/p>\n\n\n\n
openssl genrsa -out CA.key 2048
openssl genrsa -out CA.key 2048 -des3 (with password protection)<\/pre>\n\n\n\n\u200bPlease note that if someone gets this key and it’s not password protected he can generate valid certificates in your name, which is really really bad, so keep it secret!<\/strong><\/p>\n\n\n\n
Generate your CA certificate:<\/h3>\n\n\n\n
openssl req -new -x509 -extensions v3_ca -key CA.key -days 10000 -out CA.crt<\/pre>\n\n\n\n\u200bThis creates a valid CA certificate wich is valid for 10000 days. Why so long? Because when this CA expires you have to revoke and regenerate all the certificates based on this one which could be timeconsuming, but feel free to set a lower number. In order to recognize your self-signed certificates this CA must be installed on your computer which calls the website or alike. which varies between operating systems and programs.<\/span><\/p>\n\n\n\n
Generate the server certificate signing request (CSR):<\/h2>\n\n\n\n
openssl req -new -newkey rsa:2048 -key server.key -out server.csr -addext \"subjectAltName=DNS:www.domain.com,DNS:alt.dom.com,IP=1.2.3.4\"\u200b<\/pre>\n\n\n\nPlease note that you need to specify the normal domain too (domain.com) in this file and as CommonName when generating the CSR.<\/p>\n\n\n\n
Sign your certificate with a CA:<\/h2>\n\n\n\n
openssl x509 -req -in server.csr -CA CA.crt -CAkey CA.key -out server.crt -days 365 -copy_extensions copy<\/pre>\n\n\n\nQuick generate a self-signed certificate:<\/h2>\n\n\n\n
In case you want the to do quickly a certificate including multiple names and IP addresses, you can do it also in one line:<\/p>\n\n\n\n
openssl req -new -newkey rsa:2048 -days 365 -nodes -keyout server.key -out server.crt <\/code>-addext \"subjectAltName=DNS:name1,DNS:name2.dom.tld,IP:192.168.182.14\"<\/code><\/pre>\n\n\n\n\u200bAll you have to do now is copy the server.key<\/em> and server.crt<\/em> onto your machine and configure your application to use this certificates.<\/p>\n\n\n\n
