What's new in Version 10.2

  • The connecting to an SFTP server was improved by implementing the big integer algorithms using the IntXLib library.
  • The default value for the SSH packet's payload size was reduced to 32Kb in order to support more third-party SFTP clients and servers. This parameter can be tuned using the BatchSize property of both the SFTP client and the server.
  • The SFTP server was improved. The new version of this component supports more SFTP clients and implements both the client-first and the server-first approaches of starting the SSH session.
  • The SOAP message security was improved. The new ProtectionMode property, and also the Protect/Unprotect methods allow you to sign and/or encrypt XML in one line of code.
  • The SOAP encryption is available on both Win32 and Win64 platforms.
  • The Username token support was added to the SOAP message component.
  • The SOAP Timestamp generating was changed. Now you can specify the timestamp value manually or let the component to generate it automatically when composing the next request.
  • Added the certificate chain validation timeout and an options to ignore the revocation errors during the TLS/SSL handshake.
  • The RevocationFlags enumeration was replaced with a set of CertificateChainVerifyFlags flags. The new option allows tuning up the certificate chain validation more flexibly.
  • The DnsQuery component was improved. Added retrieving a domain SOA record.
  • The IP, MX, and reverse zone resolving was improved in the DnsQuery component with a help of using primary name servers for domains.
  • The independent SOCKS4 and SOCKS4a support was introduced. This new feature allows firewalls to automatically resolve the connected host name.
  • Added the ability to programmatically disable GUI message processing when working with sockets. This allows improving the components behavior when working in threads. The new option is available through the DisableGuiProcessing property.
  • The HTTP requests submission was improved when using requests with file and image attachments. Now the attachment streams are requested only once during the sending process.
  • The Imap4Server component was optimized. The new OnGetMessagesEx event allows you to filter the returned message set and do not collect all mailbox messages when handling IMAP4 commands.
  • The library provides the full RAD Studio 11.1 support.

  • The SFTP server didn't create the directory structure when saving the uploaded file - fixed.
  • Other minor fixes.

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 requires an external library clcryptext.dll that is included to the Clever Internet Suite installation.
    This library represents a managed code that is wrapped by Win32 functions.
    The source code for this library can be downloaded separately on website.
