Product Description

The suite of the Clever Internet ActiveX controls presents the most efficient and convenient way of accessing the Internet resources from your applications.
Using the Clever Internet Suite you can add instant SSL / TLS security to your Internet applications and implement many useful Internet-related features:

Downloading, uploading and submitting of the Internet-resources. Sending and receiving MIME messages. HTTP, FTP, SMTP, POP3, IMAP and NNTP client / server solutions. SSL / TLS channel with digital certificates support.

The Clever Internet ActiveX Suite represents the com-based superstructure on the Clever Internet Suite VCL edition. The main purpose of the Clever Internet suite is to provide to the end-users the higher-level interface available in any languages with com-support routines, such as Visual Basic, Visual C++, VBScript, JavaScript and many others.

Implemented Features

• Complete Client / Server solutions with full SSL / TLS support for FTP, SMTP, POP3 and IMAP4 protocols.
• TLS / SSL support for all protocol components.
• The ability to verify the client and server credential and certificates.
• HTTP Client - HTTPS (SSL / TLS) protocol, NTLM and Negotiate authentication were implemented.
• 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.
• 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.
• CertManager - 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.
• MailMessage - allows you to create and parse messages in any email format with file Attachments and Embedded pictures, the ability to determine the attachment size before saving it to the disk.
• POP3 Server - SSL / TLS support, NTLM, APOP and CRAM-MD5 authentication methods, File System message storage were implemented.
• POP3 Client - SSL / TLS support, NTLM and CRAM-MD5 authentication methods were implemented.
• SMTP Server - SSL / TLS support, NTLM, USER/PASS and CRAM-MD5 authentication methods, File System message storage were implemented.
• IMAP Client - obtaining the server Capability list; the FETCH command was improved. Now this command uses the BODY[] parameter instead of RFC822 and does not change implicitly the message /Seen flag in the same way as MS Outlook does.

The Clever Internet ActiveX Suite controls allow you to download, upload and post the Internet-resources asynchronously and obtain all related information without interfering with the main application processes.

The library includes controls which work with a single resource and the components for processing several resources simultaneously.

These controls allow you to compose / parse messages in alternative MIME format with multiple file attachments, build and send Web Form POST requests and many other features.

The Web Update control will help you keep your customers and users informed about all the latest changes and software updates available from your web-server (Internet resource). It allows receiving updates from the Internet in the way similar to the Windows Update. The whole process of checking, downloading and updating can be fully customized by defining event sequences.

The SoapMessage allows you to combine the XML SOAP message and digitally sign (DSIG) it if necessary.

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

The Clever Internet ActiveX Suite controls provide the complete Client / Server solutions for the most common Internet protocols: SMTP, POP3, IMAP4, NNTP and FTP.

All server components represent the fully functional multithreaded servers with an ability to customize the user and thread performance settings, supports the most common protocols extensions.

Components can connect to the a server via the Secure Socket Layer (SSL / TLS) channel, and capable of encoding / decoding the message content, sending file attachments and many other useful features.

Also a set of additional classes and components are available: Mail Message, HTTP Request, GZip compressor, MIME Encoder, S/MIME message, SOAP message, HTML Parser. All these component 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.
