Sorry, been busy doing too many other things this week. When I add new units to ICS, I have to update literally hundreds of package files for all the old Delphi versions we support. A few I might fire up that version of that Delphi, but it takes days to do that for all old versions so mostly it's a text editor job. But currently the old C++ packages are untouched, and I suspect they will no longer build anyway, at least not without lots of errors. So I'll remove all old C++ files from the distribution, and going forward we'll just support 10.2 and later. If someone needs support for C++ XEx, they will be better working from a newer version than an older version. My email address is in the readme8.txt file. Angus

You need to make your application SSL aware to use https, and that means using an SslContext, at least for older components. I suggest you look at the new OverbyteIcsHttpRestTst sample that uses the new OverbyteIcsSslHttpRest component, this hides the complexity of the SslContext from the application. Angus

Four new zips for Win32 and Win64 versions of OpenSSL 1.1.1b and 1..0.2r can now be downloadable from the Wiki at: http://wiki.overbyte.eu/wiki/index.php/ICS_Download . The DLLs are also included in the ICS distribution SVN and overnight zip. 1.0.2r includes a moderate severity security issue, but I don't think it can impact ICS applications. Changes in 1.1.1b may be found at https://www.openssl.org/news/openssl-1.1.1-notes.html and 1.0.2r at https://www.openssl.org/news/openssl-1.0.2-notes.html Beware 1.1.1b fixes a problem relating to multiple handshake done messages with TLSv1.3 that I reported to OpenSSL almost a year ago, and provided a workaround in ICS to fix meanwhile. Others meanwhile reported the same problem updating old applications for TLSv1.3 so OpenSSL finally changed the handshake done behaviour. My original fix still seems to work OK, but need to do more debug traces to ensure nothing unexpected has also changed with TLSv1.3. Angus

Because ICS is entirely supported by volunteers, and none of us understand C++. It would be far easier to cease support for C++. I've asked for assistance in producing C++ packages in the past, and one user kindly supplied some mostly working stuff, for 10.2 which I modified for 10.3, so renaming errors are mine. But when I can not build the packages and no-one else helps, errors are inevitable. So will some-one please email me a complete working set of 10.3 C++ package files, with whatevery changes are needed for the readme, and they will be placed in the distribution. I'm not going to work from a list of instructions I can not test. Angus

I know nothing about Kerberos, never knowingly used it. I don't believe it has any connection to OAuth, except they both end up with an access token from an authentication server. But since Windows uses Kerberos, I assume it can be used unattended without user interaction, which is not the case with OAUth which is designed for interactive web applications. So I doubt the TRestOAuth component will be much use in implementing Kerberos, although our OpenSSL implementation should handle encryption. For Windows applications, I would assume there are API calls that will handle Kerberos in the same way that NTLM authentication is handled, but again I've never look at that and have no plans to do so.

I have started a new ICS release V8.60, not finished yet but available from SVN and the daily overnight zipped snapshot at : http://wiki.overbyte.eu/wiki/index.php/ICS_Download V8.60 is a major update added several new components and sample applications created by Magenta Systems Ltd and previously distributed separately to the ICS distribution. Bundling them with ICS makes installation and updating easier, and allows existing ICS samples to make use of some the new components, such as UTF-8 file logging. There are a lot of comments in the various SVN uploads which are included in the overnight zip file. New classes added include: TIcsBlacklist TIcsBuffLogStream TIcsFindList TIcsIpStrmLog TIcsMailQueue TIcsStringBuild TIcsTimeClient TIcsTimeServer TIcsWhoisCli and there are four new sample applications that illustrate their use: OverbyteIcsMailQuTst.dpr OverbyteIcsIpStmLogTst.dpr OverbyteIcsWhoisCliTst.dpr OverbyteIcsTimeTst.dpr Also there are major updates to OverbyteIcsSslMultiWebServ.dpr which now has almost all the functionality of my commercial web server. V8.60 will also include the Magenta File Transfer components, not finshed yet. Angus
