ICS is available as source code only. You need Delphi to build the sample programs and create your own application. You will also need OpenSSL libraries if using SSL-enabled components.

ICS versions available:

  • ICS-V8 for Delphi 7 / C++ Builder 2006 to Delphi XE8, 10 Seattle, 10.1 Berlin, 10.2 Tokyo and 10.3 Rio / C++ Builder XE3 and 10.2 Tokyo with FireMonkey cross platform support for POSIX/MacOS, also IPv6 support (main development tree, 32 and 64-bit).
  • ICS-V7 for Delphi 7 / C++ Builder 2006 to Delphi / C++ Builder XE3 (stable release, no new development, please upgrade to V8).
  • ICS-V6 for Delphi 7 / C++ Builder 2006 to Delphi / C++ Builder 2007 (discontinued and obsolete, please upgrade to V7 if you do not have to support Windows versions < W2K).
  • ICS-V5 for Delphi / BCB 1 to Delphi / C++ Builder 2007 and Delphi .NET (discontinued, important bug fixes may still be backported from ICS-V7). SSL option requires at least Delphi 7 or C++ Builder 2006.

ICS News

Major changes in ICS V8.58 include:

  1. Support for OpenSSL 1.1.1 with TLSv1.3, new cryptographic algorithms and ciphers. OpenSSL 1.1.0 and 1.0.2 also supported.
  2. A new client TSslHttpRest component with Json support for all compilers and integrating cookie, SSL/TLS, content decoding, content compression and logging. There are many THttpCli improvements.
  3. A new TRestOAuth component for OAuth2 authentication including an integrated local web server.
  4. JOSE (Json Object Signing and Encryption) components supporting JWT, JWS and JWK.
  5. Simplified client SSL/TLS security and protocol settings. Support for SSL ALPN extension.
  6. A new TSslX509Certs component allowing ICS servers to automatically order, download and install SSL/TLS certificates from various suppliers, including free certificates from Let's Encrypt, and commercial certificates for DigiCert, Comodo, Thawte and GeoTrust from CertCentre AG. It also acts as a private CA to issue local certificates.

Detailed ICS 8.58 Release Notes

Major changes in ICS V8.50 include:

  1. Two new components, TIcsProxy may be used to proxy any TCP protocol, TIcsHttpProxy is a full forward and reverse HTTP/HTTPS proxy with header and body parsing and processing.
  2. Multiple SSL host support to TSslWSocketServer and other servers through IcsHosts property, each with one or two IP addresses and non-SSL and SSL port bindings, SSL certificates, private key and security level, and host name.
  3. Support for both OpenSSL 1.0.2 and 1.1.0 versions, with the DLLs digitally signed and checked during loading.
  4. ICS applications can now use PKCS12 (PFX), PKCS8 and DER binary SSL certificates to avoid manual conversions to PEM. The server certificate chain can be validated and reported before the server starts.
  5. SSL certificates and requests can be created using ECC keys which use less bandwidth than RSA keys (but which few CAs support, yet) and alternate DNS names may be used as may other extended properties.
  6. HTML content code page detection and character set conversion to Delphi unicode strings, including converting entities (like ☍).

ICS-V8 is the main development version and needed for RAD Studio XE4 and later. Older versions are only here for very old compilers and don't have current SSL support.

Latest Stable Version ICS V8.58 - recommended

This is the latest recommended version, which has been tested and used for various published ICS application. It is updated for new releases of RAD Studio and major changes. V8.58 is the version displayed when RAD Studio starts and by the main unit OverbyteIcsWSocket. Note these versions include the latest version of the OpenSSL DLLs at the time of release.

Version Control System

Using the version control repository is the best choice if you want to get live access to current development files. Overbyte uses a Subversion server and you need to use a Subversion client such as TortoiseSVN or your favorite browser. The URLs are as follows:

ICS Version SVN URL HTTP URL
ICS-V8 svn://svn.overbyte.be/ics/trunk http://svn.overbyte.be:8443/svn/ics/trunk
ICS-V7 svn://svn.overbyte.be/ics/tags/icsv7 http://svn.overbyte.be:8443/svn/ics/tags/icsv7
ICS-V6 svn://svn.overbyte.be/ics/tags/v6_obsolete http://svn.overbyte.be:8443/svn/ics/tags/v6_obsolete
ICS-V5 svn://svn.overbyte.be/icsv5 http://svn.overbyte.be:8443/svn/icsv5

Use username = ics and password = ics for read access. Write access is only available to TeamICS.

Download OpenSSL Binaries (required for SSL-enabled components)

Please note older versions of the ICS source code had an internal check to only allow loading of the latest OpenSSL it was tested with, so you could not use new DLLs with an old application without recompiling with the latest version of ICS first. But ICS V8.16 on 25th March 2015 relaxed this check so that minor versions with a letter suffix that don't add new features or break anything (in theory) are now supported. This worked for about a year, but OpenSSL 1.0.2g and 1.0.1s, and later, no longer support SSLv2 which means old versions of ICS can no longer load them, so V8.24 dated 3rd March 2016 or later is now needed for these current and newer OpenSSL releases. ICS V8.24 and later will currently support up to 1.0.2z, and V8.33 and later up to 1.1.0z. Also note ICS V8 no longer supports 1.0.1 and earlier.

OpenSSL removed support for the obsolete SSLv2 protocol in 2016 from 1.0.1s and 1.0.2g and ICS V8.35 finally removed SSLv2 support even with older OpenSSL releases.

OpenSSL 1.0.2 and later are only supported by ICS v8, v7 is no longer updated for new OpenSSL versions. The 64-bit DLLs are only for use with Delphi applications compiled for the 64-bit platform, the 32-bit DLLs work on both 32-bit and 64-bit Windows with 32-bit applications. Note that ICS V8.24 dated 3rd March 2016 and later included the latest OpenSSL 1.0.2 Win32 files to avoid a separate download. This was a long term support version for which support ceases at the end of 2019.

OpenSSL 1.1.0 is a major new version with new DLL file names and many different exports, and requires ICS V8.33 dated 29th August 2016, or later. Generally, applications need not be changed, but there are several new SSL features in V8.33 that should be studied. Beware the OpenSSL 1.1.0 and later DLLs may not be used with any existing SSL applications until they have been specifically updated to support all the changes. ICS V8.33 to V8.56 include the Win32 and Win64 OpenSSL 1.1.0 files. Support ceases for 1.1.0 in September 2019.

OpenSSL 1.1.1 is the latest long term support version and adds support for TLSv1.3 RFC8446 and various new cryptographic private key and hash digest types. Delphi applications require ICS V8.57 or later. ICS V8.57 and later include the Win32 and Win64 OpenSSL 1.1.1 files. This version will be supported until 2023.

Firefox version 63 and Chrome 71 both support TLSv1.3 final RFC8446, note Chrome has settings for older beta versions that must be disabled.

The OpenSSL DLLs and EXE files included in the latest zips below are digitally code signed 'Open Source Developer, François PIETTE', the lead developer for ICS. ICS V8.38 and later check the DLLs are correctly signed when opening them.

Download OpenSSL Binaries (alternative)

OpenSSL website also links to Win32OpenSSL website providing another build of Win32 DLL binaries. Note note that unlike the builds above builds on that site may have dependencies on Visual C++ 2008 Redistributables (to keep dll files smaller) so make sure you include all the required (and correct) redistributable files in your software installation. You probably don't have to care about that if you use binaries above at the cost of slightly larger DLLs. Also note that site does not keep archives of older versions so you may want to watch their page if you prefer their binaries.

Browser Demo Application using HtmlViewer

This is an example internet browser using the HtmlViewer component from GitHub (11.8).

The browser demo is in the ICS nightly zip, in the folder samples\delphi\browserdemo, the project is FrameBrowserIcs.dpr. An executable version of the new demo may also be downloaded from here, built with HtmlViewer 11.8 and ICS V8.59, using Delphi 10.2 Tokyo. Beware HtmlViewer 11.8 only appears to support up to Delphi 10 Seattle, I took paackages and files from master to build in 10.2 Tokyo.

Download
Executable Browser Demo

The HtmlViewer component must be downloaded and installed before the demo can be built. The demo is based on FrameBrowserIndy project but with various enhancements, specifically display of all HTTP, SSL and some or all HTML traffic which makes it very useful for debugging the THttpCli component.

The Options, Settings window allow the SSL security level to be adjusted to various TLS and cipher variations, which can be useful testing web sites that ICS has difficulty accessing.

The project is a good basic browser for HTML4, but does not support any scripting, so some sites without backward compatibility may appear strange.
