Using TLS1.2 with IBMi custom agent software

I have a client that has a custom server / agent software package. The
server runs on windows. The agent runs on the IBMi and some other
platforms. They want to add TLS1.2 protocol to the communication and I have
to do the IBMi side. I'm apparently not googling with the right keywords
because I'm not finding any details on how to implement it. Are there code
changes that need to be made? It is just a different port and the
encryption / decryption automatically happens? I'm lost. Can someone point
me in the right direction for what changes have to be made to the IBMi agent
for TLS1.2? I'll take web links, keywords for google searches, of anything
else that get me heading in the right direction. I am open to doing a teams
meeting if that would be easier. Just send me an offline request with times
that you are available.



Thanks in advance.
