    Hi Lee,

     

    First of all, good job with the ApexDC, it's a compfortable and stable client, i have use it over 2 years without any problems.

    In the next few weeks we change the TLS protocal in Luadch from TLSv1 to TLSv1.2 and i think the reason for this should be clear.

    With TLSv1.2 we can use ciphers like ECDHE-RSA-AES256-GCM-SHA384 or others that only runs with TSLv1.2. In this context there are some problems we need to solve:

     

    Problem 1: The most client based on DC++ (ApexDC too) and DC++ has indeed TLSv1.2 support but these guys disable it, don't ask me why^^ And so the most DC++ based clients has a disabled TLSv1.2 too (inherited). And as if that were not enough, here the next problem:

     

    Problem 2: DC++ has a limitation to AES128 bit ciphers (they call them "reasonable TLS ciphersuites" no joke, here are the code: http://sourceforge.net/p/dcplusplus/code/ci/5c967fcb1ff9a0aa9886a8e65cdbfab1afe9bda4/) and yes the most DC++ based clients has this problem too (inherited).

     

    Whatever, the AirDC developers disabled this imho rediculous limitation (here are the code: https://github.com/airdcpp/airgit/commit/b0826716ae4ae22fc006e5aecf06d9a2e99f7310) and supports TLSv1.2 in the new 3.00a versions too.

    Here are a small list with popular clients:

     

       Windows Clients:

          DC++                TLSv1.2 Support:  YES in Version: 0.850 or higher (but uses a AES128 cipher limitation)
          AirDC++            TLSv1.2 Support:  YES in Version: 3.00a-29 or higher (no cipher limitation)
          StrongDC++      TLSv1.2 Support:  NO
          ApexDC++        TLSv1.2 Support:  NO
          RSX++              TLSv1.2 Support:  NO
          SmVDC++         TLSv1.2 Support:  NO
          DC@fe++          TLSv1.2 Support:  NO

        Linux/Unix Clients:

          jucy (uc)             TLSv1.2 Support:  YES in Version: 0.87 or higher (no cipher limitation)
          EiskaltDC++       TLSv1.2 Support:  NO
          LinuxDC++         TLSv1.2 Support:  NO
          NCurses (ncdc)  TLSv1.2 Support:  YES in Version: 1.19.1 or higher (no cipher limitation)
          AirDC Nano        TLSv1.2 Support:  NO (coming soon with no cipher limitation)

     

     

    The question what i have to you Lee: Will ApexDC supports TLSv1.2 in the next version? and has it a cipher limitation like DC++?
