Over the past year occasionally visited websites without https and noticed some login forms show a dropdown informing me I’m not on https. Some fancy newly upgraded browser I thought, ey! That plus internet is going forward and forcing or encouraging to use ssl configured websites. Good. One evening said “hey I should make it happen to my local with let’s encrypt”. Apparently it needs to be publicly available. For local projects I just need to follow few ‘simple’ steps.


Let’s create self-signed certificate

$ openssl genrsa -des3 -passout pass:password -out server.pass.key 2048
$ openssl rsa -passin pass:password -in server.pass.key -out server.key
$ rm server.pass.key
$ openssl req -new -key server.key -out server.csr
A challenge password []:
$ openssl x509 -req -sha256 -days 365 -in server.csr -signkey server.key -out server.crt

For password challenge can leave blank and just hit enter.

Extra certificate

$ sudo openssl dhparam -out /etc/ssl/certs/dhparam.pem 2048
