Clever Internet Suite 9.3

# Clever Internet Suite version 9.3

These Internet components give you everything you need to jumpstart your Internet development without any external dependencies. The suite of Internet Components contain over fifty components which are constantly refined and improved.

The Clever Internet Suite components allow you to compose and parse messages in MIME format with multiple file attachments, build and send Web Form POST requests and many other features.

The SMTP, POP3 and IMAP clients allow you to send and retrieve email messages over the Internet.

All server components represent the fully functional multithreaded servers with the ability to customize the connection settings, support the most common protocols extensions.

Using the Clever Internet Suite you can add instant SSL / TLS / SSH security to your Internet applications and implement many useful Internet-related features:

- Downloading, uploading and submitting of the Internet-resources.
- Sending and receiving e-mail messages with DKIM signatures.
- HTTP, FTP, SMTP, POP3, IMAP and NNTP client / server solutions.
- secure channel with X509 certificates support.
- OAUTH 2.0 authorization.
- SOAP Security and many more.

In this new version 9.3 we have added the RAD Studio 10.3 Rio support. The updated version of the SOAP component provides the SOAP XOP messages support. The MIME Parameter Continuation and Header Encoding Extensions were implemented, as well.

Starting from the version 8.0 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 Help documentation is included to the Clever Internet Suite installation and also available at our website: Clever Internet Suite downloads
