[twsocket] What are possible dangers using ICS-SSL without SSL version check

2011-04-03 Thread Dimitris Botsis
Hi all, what are the possible problems and dangers that may come when using ICS without version check for SSL libraries (enable $DEFINE NO_OSSL_VERSION_CHECK in OverbyteIcsSslDefs.inc) ? The latest SSL libs that are available, are much smaller than the ones that 0.9.8x that are available

The latest SSL libs that are available, are much smaller than the ones that 0.9.8x that are available from http://wiki.overbyte.be/wiki/index.php/ICS_Download. The size of the SSL DLLs varies depending on whether they contain large C run time libraries. The ICS versions are self

Thank you Angus. Additionally I used UPX and reduced size of libraries - now it's better. On 3/4/2011 1:53 μμ, Angus Robertson - Magenta Systems Ltd wrote: The latest SSL libs that are available, are much smaller than the ones that 0.9.8x that are available from

I wondered why it is so big problem to have a large exe? Installers already compress well for bandwidth and an average 1TB HDD costs less than $100! SZ On Sun, Apr 3, 2011 at 6:15 PM, Dimitris Botsis db...@otenet.gr wrote: On 3/4/2011 5:12 μμ, Arno Garrels wrote: Angus Robertson - Magenta

It definitely depends on the project. Even 100 KBytes less make significant performance to my client-server auto-update application. Both server has less bytes to send to 100 concurrent connected clients and client can download much faster - there are still some clients using dial-up or GPRS

It is definitely possible to have issues with UPX but I would say that's a bit too sensitive heuristics. With better (read: paid) anti-viri programs I never had any issues - they recognize UPX and unpack it properly and check for whatever is inside. Only AVG and similar software (free versions)

Also, is there a mechanism (in ICS) to check for invalid root certificates (regarding the recent SSL issue with bad Comodo certificates)? -- To unsubscribe or change your settings for TWSocket mailing list please goto http://lists.elists.org/cgi-bin/mailman/listinfo/twsocket Visit our website at
