A Delphi zlib 1.1.4 implementation for fastest performance, including targeted P6 code generation, 64bit alignment, source changes and optimizations following Borland# C++ full standards adherence, and a Delphi added low level copy memory function to speedup typical strings management. Embed the newest zlib 1.1.4 objects into your programs without using external dlls, take a look into the example seeing how to work with streams and strings.
  • new: implemented the deflate algorithm
  • new: added simple procedure: ZSendToBrowser(string)

    This component links to Lzh component and allows you to pack multiple files to a single Paradox table, like ZIP archive is doing. It encapsulate basic procedures as add a new file to archive, remove an existent file from archive, open an existent file from archive, etc. It requires the Lzh component which actually is included in ZIP. If you want to get the latest free version of Lzh component try the Link section on Delphi Home Page (we recommend you Delphi Super Page component archive).

    The DelphiZlib package contains a TGzip, TCrc32 and TAdler32 component. Now you can add GZip, Gunzip, Crc32 and Aler32 functionality to your programs. The code uses the Zlib library and is therefore free from any licences. No dll's are needed. Note that this package used to be called DelphiGzip.

    These sources provide a Delphi (2-8 and 2005) direct interface to PGP requiring a preceding (!) full installation of PGP 6.5.x, 7.x, 8.x or 9.x.

    Available capabilities:

    • Encoding and decoding (encryption/decryption/signing/verifying)
    • Creating and verifying file detached (Open)PGP signatures
    • Importing, exporting, revoking, deleting keys & certificates
    • Several key & certificate management functions
    • Key & certificate generation (DH/DSS, RSA)
    • x.509 certificate & S/MIME support
    • Keyserver functions
    • Some utilities

    New in Version 4.5.2:

    • Signing data without using PGP's passphrase dialog in TPGPEncode shouldn't cause access violations anymore.
    • CreateX509CertificateFromRequest in X509Funcs.pas now returns a CertPropsList instead of a CertPropsRec.
    • GetKeySetByAnyID in KeyFuncs.pas doesn't try to process non-empty blank IDs (spaces, e.g.) anymore.
    • PGP's dialog for certificate selection shouldn't occasionally hide in background anymore.

    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, ... everything) 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.

    ZLBArchive a wrapper component for the ZLIB compression routines to create ZIP like files. It does not create .zip files! Lots of routines for adding and extracting files from the ZLB file format. This version now has greater support for large files. This component is freeware and the author requests that any modifications be mailed back to him.
