I am currently trying to debug and figure out of how the network aspect of an application work, however the traffic is encrypted, and only TLS packets are available via wireshark. I have heard that there are some programs (like oSpy, but this one works for 32 bits programs only) that are capable of directly hook to the encrypt/decrypt functions of Windows' dll and read traffic this way. If anyone knew a clean, new version of such "SSL dll hook", I'd be glad to hear about it.
PS: I can't use a proxy too, because my app obviously won't accept the proxy's certificate. I don't have access to the server's master key either ofc, and reading the client's master key would be a huge mess I don't want to get into.
