Clever Internet Suite version 9.2 overview

Clever Internet Suite version 9.2

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 the new version 9.2 we have added a set of strong cryptographic algorithms. The updated versions of the SFTP and SMIME components provide a set of advanced cryptographic features. The totally redesigned BounceChecker component extracts all email addresses from the message by using of the regular expressions syntax, analyzes the message content, and indicates, if the message contains the non-delivery report.

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

What's new in version 9.2

  • The full RAD Studio 10.2.3 Tokyo support.

The updated version of the component allows you to obtain an information about the used cryptographic algorithms, the signing key length, and digital certificates before verifying and decrypting the message.
  • The updated Encryptor component allows you to extract the used cryptographic algorithms, key length, and other information from the protected file. A set of overloaded methods was added.
  • The IMAP4 UTF7 name encoding was added. The implemented feature allows you to use international mailbox names with both the client and server components.
  • IMAP4 client - support for multiple untagged SEARCH responses was added.
  • IMAP4 client - the UnseenMessages property was removed from the TclImap4MailBoxInfo class.
  • The updated OAuth component allows you to refresh the authorization token and specify custom request fields while negotiating with the OAUTH server.
  • BounceChecker - The updated component extracts all email addresses from the message by using of the regular expressions syntax, analyzes the message content, and indicates, if the message contains the non-delivery report.
  • The Encode/Decode methods of the Encoder component were renamed and reorganized in order to improve the interface and usability.
  • Downloader, Uploader, MultiDownloader, MultiUploader, NewsChecker - the URL_COMPONENTS structure was replaced with the TclUrlParser class, the full Unicode support was implemented.
  • SSH engine - the support for the Global Request Handling was implemented.
