You must adhere to the terms of the licence. You don't say which version 
of OpenSSL you are using (different licences apply depending on the 
version). Assuming you are on 3.0+ then Apache v2 applies:

https://www.openssl.org/source/apache-license-2.0.txt

You must adhere to all the terms, but I draw your particular attention 
to section 4 (redistribution) which seems relevant here.

You must also be sure to adhere to our trademark policy. You can read 
that here:

https://www.openssl.org/policies/general/TrademarkPolicy.html

As long as you are doing all of those things then you can make any 
changes you like. I can't give you advice on what specific changes would 
comply or not comply with the licence - you must make that determination 
yourself. You might want to engage a lawyer to help you.
