SSL from squarespace to my EC2

[manmohan3108]

I am newly learning domains and ssl.

I have a spring boot application running in my EC2 and mapped its elastic ip to my domain in Squarespace.

Can someone please tell, if the ssl coming with Squarespace only for default squarespace websites?

Can I get and use the ssl provided by squarespace, to setup https in my spring boot jar running on my ec2 server whose elastic ip is mapped to my domain in Squarespace DNS settings?
