I have two files:
mycer.cermykey.keyI need to create a SslContext to connect to another server via SSL using Java.
I'm trying to find out how I can create the SslContext object directly from those files.
This post may be duplicated, but I tried to find a clear explanation with an example to create the SslContext, but didn't find something clear.

You can use OpenSSL to create a private key and a certificate signing request (CSR) that can be transformed into a certificate after it is signed by a certificate authority (CA).
You cannot generate private key from public key but you can generate public key from the private key using puttygen. As @alfasin mentioned if you could generate the private key from public key then RSA would be useless and this would make you vulnerable to attack.
Get a certificate in p12 format, as far I know you can not use cert file, there are utilities to do that (like openssl) or the source (from where you generated downloaded the certificate) can give you a p12 format.
openssl pkcs12 -export -in mycer.crt -inkey mykey.key -out mycer.p12 -name "mycer"
And then check the below url, it should contain the information you want.
Java HTTPS client certificate authentication
Hopefully it helps!
