DIZipWriter is a high performance zipping component with strong AES encryption for Borland Delphi. It creates standard ZIP archives as well as high-security archives with up to 256-bit key size introduced by WinZip 9. There is no other known Delphi component supporting this level of ZIP encryption.

Another unique feature of DIZipWriter is its TStream based interface, which allows to:

  • Create ZIP archives as streams, including files, memory streams, BLOB streams, etc.
  • Create entire ZIP archives in memory or write them directly to database BLOBs.
  • Add ZIP entries from streams using the CopyFrom procedure.
  • Directly stream objects to ZIP archives using the SaveToStream procedure.

In addition to streams, DIZipWriter also works with

  • files, including long file names and relative paths
  • strings
  • memory buffers and records.

For optimal performance, DIZipWriter writes all data straight to the ZIP archive and uses no temporary files. Its footprint and memory requirements and are very small. Includes HTML help and example projects.

FlexCompress is a high-speed compression library developed to provide archive functionality for your applications. This solution provides flexible compression and strong encryption algorithms that allows you to integrate archiving or backup features into your programs in a fast and easy way.

FlexCompress includes our new unique technology, a transaction system. This innovative solution gives you a rapid and simple way of updating archive files providing data integrity like a reliable database system.
Key features:
- Creates archive files of custom format having better compression rate than WinZip and WinRar
- Native VCL; no DLLs; no OCXs
- Adds, moves, extracts, deletes, updates, tests, refreshes a group of files by a single operation
- Creates encrypted archives using strong encryption algorithms
- Creates self-extracting (SFX) archives
- Performs regularly archive updates using transactions that allows canceling all modifications at any time in case of some failures. Also this technology optimizes the speed of the archive modification
- Compresses large files with low memory consumption

VCL package for easy adding multiuser, privileges and user rights functionality to your Delphi and C++ Builder apps. Allows you to control the user access to your app GUI components (menus, buttons, check boxes, radio groups, etc. everything connected to an Action) as well as to non visual functionalities. Just drag/drop and connect and you get a securized application. The built-in Designer, activated by double clicking Security Component, allows you automatically to generate your Security Model at design time from bounded Action Lists. You can add non TAction related securized functionalities by right clicking parent node and select "New Checkable Node". You can change the Security model hierarchy by adding (right click and select "New Hierarchical Node") and deleting nodes, as well as drag/drop nodes.... All this at design-time without single line of coding. Users and their security privileges can be defined at run time, by choosing "Security" button from your Password dialog window, provided that you have Supervisor rights. Regular users can only consult their privileges (and the security hierarchy) and change their password. Key Features: Controls the user access to GUI components of the application Ease of use - drag/drop and connect and get fully functional multiuser app Change security template at design time or on fly Change users profile on fly Add and remove securized items at design time or on fly Securize your non GUI functionalities Much more... For Delphi and C++ Builder; shareware; sources on Purchase/Registration The library consists of three component: TabSecurity - control center encapsulating the application security template, implementing all Security Builder functionalities, TabActionList - ActionList control providing a connection to abSecurity component and to it's control center functionalities, TabAction - an TAction derivative, adding the ability to Enable/Disable and change the Visible/Invisible status of bounded GUI elements depending upon current user rights.
