While you are waiting for getting help, here are some tips to improve your experience:

Code is much easier to read if posted with syntax highlighting and proper formatting.

If nobody is calling back, that usually means that your question was not well asked and hence nobody feels confident enough answering. Try to use your time to elaborate, provide details, context, more code, examples and maybe some screenshots. With enough info, someone knows the answer for sure.

Don't forget to close your thread using the command </help-thread close:1027500463647621170> when your question has been answered, thanks.

gprc

or websockets but try grpc first

essentially have a client / server architecture

[little lichen]

i mean like not between servers but like game on pc

[fierce river]

depends
if you only want an app to launch another, then launch it and pass the args

[little lichen]

but passing through args is not too secure, it can be captured

i can encrypt string i guess

but isnt there some better way?

like class loader?

launcher can class load game

like both are in java

[fiery glacier]

jni?

use native methods

still someone will eventually reverse engineer it if they really want too

[fierce river]

if this isn't secure, then nothing is

what do you want to pass

[little lichen]

user name and auth data

[fierce river]

only pass a token

if it is on the same machine, nothing bad should happen

@little lichen

[little lichen]

it can be easier to crack etc

[fierce river]

no

[little lichen]

processhacker sees arguments

[fierce river]

if you pass a token you have total control about its lifetime

you can decide that it can be used once and expire after a few seconds

and now, even if someone manages to hack the machine, even if it manage to somehow get the args which is probably impossible already, he can't even use it

but note that doing all of that seems pretty hard for a hacker already

you can also use env variables

Closed the thread.

[fierce river]

and also you can try what Filip said @little lichen
you can have a socket which is interacted by the same machine
