PKWARE solutions utilize strong encryption so there is nothing that can be done if you lose or forget your password. It is important to remember your password as PKWARE has no special means for “getting around” the encryption and may not be able to assist in the recovery of an encrypted file.

The DCL provides data compression and decompression functions only. With it you can compress a stream of data and send the compressed data to the destination of your choice. Destinations include memory buffers, other processes, or files in any format you define. The DCL does not directly support the .ZIP file format. The Toolkit will allow you to use all the functionality of PKZIP/SecureZIP to create and manage zip files using data compression and/or data security.

Yes, files created by the PKZIP/SecureZIP Toolkit can be uncompressed by PKZIP or SecureZIP for Windows®.

SecureZIP Toolkit offers all the options of PKZIP Toolkit but also includes the ability to use strong encryption, digital certificates, digital signatures, LDAP integration, and the ability to make Self-Extracting Files (SFX).

Our SDKs can be used with most programming languages; however, you may need to create an integration wrapper to interface between the SDK and your application if you cannot directly call C or C++ routines. If you are using a .NET language, PKWARE provides a .NET wrapper with the PKZIP/SecureZIP toolkit.

All errors are documented in pkstatus.h. This file can be found within the Include folder located in the installation directory. You can also find all errors in the product documentation.

The evaluation is fully functional, offering all features of the product. The evaluation can only be used for 30 days from installation.

The DCL and Toolkit are compiled as 32-bit libraries. They can be used within any application that can link with a 32-bit library. Most 32-bit applications will run unmodified on a 64-bit platform. The PKZIP and SecureZIP toolkit are compiled both as 32-bit and 64-bit libraries.
