The Clever Internet Suite v 9.6 includes updates for all supported editions: RAD Studio VCL, .NET and ActiveX.
Starting from now, all three editions provide the same functionality and almost the same list of advanced Components

New Features
RAD Studio 10.4 Sydney support was implemented.
Certificate management improvements: new Certificate properties were added, new functions to search certificates by issuers, serial numbers, and subjects were implemented.
Starting from version 9.5, you can specify a certificate serial number as a big-integer string.
New encryption algorithms were added to the SFTP public-key authorization: aes-128-cbc, aes-192-cbc, aes-256-cbc, aes-128-ctr, aes-192-ctr, and aes-256-ctr.
HTTP RIO improvements: the new version 9.6 extracts the SOAP encoding from WSDL, and there is no need to specify the document/literal encoding manually.
Logger improvements: the maximum dump size limit was implemented.
The MailMessage.MessageText property was improved to support iPhone Emails with attached pictures.
SOAP Security improvements: the AutoCreate mode was implemented for timestamps, the ability to verify message timestamps was introduced, loading response SOAP namespaces was added.
New encrypted key formats were added to the XML security engine: X509Data for issuer-serials, subject key identifiers, subjects, and encoded certificates.
The ConnectTimeout property was added to all Internet clients components.
The updated SFTP component provides the ability to specify a character encoding for paths.
Added the ability to obtain an SFTP host-key information.

Global Notes
We have joined installations for all versions of RAD Studio (XE...XE8, 10, 10.1, 10.2, 10.3, and 10.4 Sydney, Delphi and C++Builder) in one single installer.
You can Download Clever Internet Suite and install on any desired version of RAD Studio IDE.
.NET Compact Framework is no longer supported. The minimum .NET Framework version is 4.0. Download Clever Internet .NET Suite
The library was splitted on design-time and runtime packages. Starting from now, the components can be used by RAD Studio form designer in 64-bit projects.
The basic socket components were replaced and improved. The class inheritance was changed. Please see the Help documentation for more details.
The source code structure was changed. Starting from now, the sources are placed in the following folders: common, design, packages, resources and ssh.
To compile the source code project, navigate to the packages folder, choose the corresponding IDE version subfolder, e.g., D103 for Delphi 10.3 Rio,
open and compile both the clinetsuite_103.dproj and dcl_clinetsuite_103.dproj projects. Finally, install dcl_clinetsuite_103.dproj to your RAD Studio IDE.
The SSH and SFTP component files were moved to the main clinetsuite package. The clinetsuitessh package was removed from the installation.
A set of cryptographic classes were added: Cipher (and its descendants), Hash, Mac, KeyExchange, Signature and many more.
Known problems and restrictions
FTP client and server - data connection uses IpV4 protocol only.
Socks5 firewall - supports IpV4 only.
The HTTP RIO component is available only starting from Delphi 2005 / C++Builder 2006.
The SOAP encryption is available only on Win32 platform.
The SOAP encryption requires an external library clcryptext.dll that is included to the Clever Internet Suite installation.
This library represents managed code that is wrapped by Win32 functions.
The source code for this library can be downloaded separately on www.clevercomponents.com website.
