Thanks it works!
But why it is written, that lnet had no dependecies (except FPC, and Lazarus)?
lNet itself has no dependencies, and produces "smartlinked" code with FPC.
OpenSSL support however is a functionality requiring external library and if you use it (TLSSLSession) then you will need this library. One could write a SSL library in FPC for example, but that's a huge undertaking and is also risky (openSSL is tried and true, and responds to security issues).
For distribution needs, you can include the openSSL library (dll) for windows in your application provided you comply with their license (I think a readme might be sufficient).
