How to get a self-written ssl certificate?

Question

Digital certificates

I remember a long time ago I generated a self-written ssl certificate using some site, now I can’t find it, can you tell me this kind of site where you can enter a domain and other information and get a self-written ssl certificate?

Answer 1

Use openssl and life will be easier:
openssl req -x509 -newkey rsa:2048 -keyout privkey.pem -out cert.pem -days 1095 -nodes
privkey.pem - private key
cert.pem - certificate
