Clever Internet ActiveX Suite 9.1 overview

Clever Internet ActiveX Suite version 9.1

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 9.1 we have updated the MailMessage,SoapMessage and SFtp components, fixed issues in the TLS and cryptography engines.

What's new in version 9.1

  • MailMessage - RFC 5987 support added, file names in UTF-8 format implemented.
  • A new 64-bit OCX was added to the installation
  • New CryptEncoder component - provides methods for data encoding and decoding in PEM and SSH2 cryptographic formats.
  • SFTP client - the public key authorization was implemented, the following new algorithms were added:
    diffie-hellman-group-exchange-sha256 and diffie-hellman-group14-sha1 for key exchange functionality;
    rsa-sha2-256 - server host key algorithm; aes256-ctr, aes192-ctr, aes128-ctr, aes256-cbc, aes192-cbc ,aes128-cbc - data encryption algorithms;
    hmac-sha2-256 - for message authentication algorithms; sha2-256 - hash calculation algorithms.
  • DKIM component - the Config property was added. This property allows you to configure the used encryption and signature algorithms.
    The signature verification is disabled when retrieving the message header.
  • HTTP client - the TLS1.2 option was enabled by default.
  • EPP server - the UTF-8 encoding was added.
  • All TCP-based server components (SMTP, POP3, IMAP4, FTP, etc.) - the new CharSet property allows you to specify the desired character encoding for received commands and server responses.
  • All UDP-based client components (DNS query, etc.) - the new CharSet property allows you to specify the desired character encoding transmitted datagrams.
  • HTTP request component - was redesigned, the Items indexed property now represents the HTTP request items collection object.
  • The SSH and SFTP component files were moved to the main clinetsuite package. The clinetsuitessh package was removed from the installation.

Implemented Features

  • HTTP RIO component with SOAP Security support.
  • Simple HTTP Server component.
  • Complete Client / Server solutions with full SSL / TLS support for FTP, SMTP, POP3 and IMAP4 protocols.
  • TLS / SSL support for all protocol components.
  • SSH support for the SFTP protocol.
  • Royalty free licensing. Free Unlimited Email support.
  • Fully-indexed help documentation. Delphi and C++Builder demos code.
  • Send / receive HTTP requests in JSON format.
  • International domain names for HTTP components.
  • The ability to verify the client and server credentials and certificates.
  • HTTP Client - HTTPS (SSL / TLS) protocol, NTLM and Negotiate authentication.
  • FTP, SMTP, POP3, IMAP, NNTP clients - three new TLS modes - implicit, explicit and automatic. STARTTLS command support.
  • NTLM authentication for all mail clients was added: POP3, SMTP, IMAP. When the UseSasl option enabled,
    these components automatically determine and use the most secured authentication method.
  • POP3, SMTP clients - working with GMAIL service with OAUTH 2.0 authorization.
  • Fully functional HTTP / HTTPS client.
  • FTP Client - SSL / TLS support, the ability to set FTP file attributes and permissions were added. FTP FXP (Site to Site) transfer mode.
  • FTP Server - custom events for all operations with files and directories on the server, the possibility to customize all file-related operations
    including compressing and uncompressing functionality. Virtual File System.
  • Events for implementing the mail sending / receiving progress with the ability to interrupt the process.
  • Creating self-signed certificates, working with any type of certificate store including current user stores, local machine stores, file stores, registry stores and so on.
  • Creating and parsing email messages in any format with file Attachments and Embedded pictures, the ability to determine the attachment size before saving it to the disk.
  • POP3, SMTP, IMAP4 servers - SSL / TLS support, NTLM, APOP and CRAM-MD5 authentication methods, File System message storage.
  • POP3, SMTP and IMAP4 clients - SSL / TLS support, NTLM and CRAM-MD5 authentication methods.
  • Web DAV - manages remote files and folders on a web server.
  • DNS Query - queries a DNS server for records. This component can retrieve the mail exchange domain (MX records), resolve the host IP,
    retrieve the information about name servers and many other information from the DNS server.
  • DNS Server - implements fully functional DNS server and allows you to both manage handed DNS zones and cache non-authoritative DNS records.
  • SMTP Relay - implements a SMTP Relay agent. With SMTP relay, a mail message may pass through a number of intermediate relay or gateway hosts on its path from sender to recipient.
  • HTML Parser - parse HTML Tags: links, images, tables, meta tags and many more.
  • GZip compressor component - provides compressing / uncompressing feature when transmitting data over the Internet, storing data in to a file, database and many more.
  • RSS client - is used for creating, retrieving, and editing RSS feeds.
  • Email validation components - allow you to validate recipients email addresses, mailbox availability and also handle bounced emails.

Also a set of additional classes and components are available: Mail Message, HTTP Request, GZip compressor, MIME Encoder, S/MIME message, HTML Parser.
All these components make the application development process easy and clean. You can use these components separately from the main protocol components with any other library and even with your own socket implementation.

Fixed bugs

  • The HttpAuthorization is not thread-safe - fixed.
  • SFTP file permissions parsing errors were fixed, IsDir file attribute works correctly.
  • TLS engine - INCOMPLETE_MESSAGE error occurred - fixed.
  • RSA key for RSA-SHA-256 algorithm was imported incorrectly - fixed.
  • SFTP large directory listing errors, the problems with receiving of incloplete SSH packets was fixed.
  • SOAP Signing takes a lot of time - fixed.

Known problems and restrictions

  • FTP client and server - data connection uses IpV4 protocol only.
  • Socks5 firewall - supports IpV4 only.
  • 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 at www.clevercomponents.com website.
