Create Multi-Domain Self-Signed SSL Certificates
A tool for creating self signed multi-domain (and wildcard) SSL certificates for the purposes of development! For production you should use certificates verified by a third party.
Normally you would have remember and do this of all on the command line:
openssl genrsa -out multidomain.key 2048 openssl req -new -key multidomain.key -out multidomain.csr echo "subjectAltName=DNS:first.com,DNS:*.second.com,DNS:another.io,IP:10.0.0.0" > domain_extensions openssl x509 -req -in multidomain.csr -signkey multidomain.key -extfile domain_extensions -out multidomain.crt -days 10000 rm multidomain.csr domain_extensions
That's difficult. So instead we use PHP, and we don't even need openssl. It works on Windows computers too!
composer require polycademy/sslcreator:*
sslcreator primary.com secondary.com *.wildcard.com -f multidomain -b 2048
Results in this:
Registering these domains: - primary.com - secondary.com - *.wildcard.com Generating Key Pair Generating Certificate Signing Request Signing the Certificate Saving Key and Certificate at Current Working Directory Saved as: - ./multidomain.key - ./multidomain.crt
Need a lot of domains? Just point to a JSON file.
sslcreator -j ./domains.json -f multidomain -b 1024
The JSON file needs to be:
[ "primarydomain.com", "anotherdomain.com", "*.wildcard.com" ]
