          This will make contexts using ``SSLv23_METHOD``. This is
          because OpenSSL thought it would be a good idea to have
          ``TLSv1_METHOD`` mean "only use TLSv1.0" -- specifically, it
          disables TLSv1.2. Since we don't want to use SSLv2 and v3, we
          set OP_NO_SSLv2|OP_NO_SSLv3. Additionally, we set
          OP_SINGLE_DH_USE.
