The SecureZIP® Toolkit for Windows and SecureZIP Toolkit for Java are our premier developer solutions that combine advanced ZIP archive management with strong data security functionality. OpenPGP support is available in the Enterprise edition of SecureZIP Toolkit for Windows and in the SecureZIP Toolkit for Java.

The PKZIP® Toolkit for Windows includes PKWARE’s industry-leading Data Compression Library, as well as the ability to create and extract data from a wide variety of archive types in addition to ZIP.

The PKWARE® Data Compression Library (DCL) for Windows® provides a high-speed interface for compressing and decompressing data within applications when ZIP archiving is not required.

PKZIP Toolkit for Windows

The PKZIP Toolkit for Windows includes PKWARE®’s industry-leading data compression libraries and adds the ability to create different types of data file archives, including ZIP archives, as well as extracting data from a large selection of archive types.

The PKZIP Toolkit for Windows also exposes many of the advanced archive management functions previously only available with PKWARE’s end-user applications. In addition to ZIP archives, the Toolkit can create BZIP2 and GZIP compressed file archives, as well as TAR, UUENCODE, and XXENCODE archives. Extraction capabilities include all these types, plus extraction from CAB, BinHex, ARJ, LZH, and RAR archives. Additionally, ZIP files created with the Toolkit can be extracted on any PKZIP-supported platform (Windows®, UNIX®/Linux®, i5/OS®, or z/OS®).

The PKZIP Toolkit for Windows includes:

• Shred files using DOD 5220 standard, providing an additional level of configurability for organizations that want to ensure that deleted files are not recoverable.
• All the compression and decompression capabilities of the DCL.
• Available for Windows 32-bit and 64-bit platforms as dynamic link libraries.
• Archive creation using ZIP, GZIP, TAR, BZIP2, UUENCODE, or XXENCODE.
• Extraction of ZIP, GZIP, TAR, BZIP2, UUENCODE, XXENCODE, CAB, BinHex, ARJ, LZH, and RAR archives.
• Wavpack extraction support
• Immediate and deferred archive operation.
• File shredding.
• Text line translation.
• Path storage.
• Creation of target folders.
• Progress notification.
• Multithread-enabled.
• C/C++ interface, combining easy integration with high performance. 
• .NET interface
• UTF-8 International File Name Storage

PKWARE Data Compression Library

The PKWARE® Data Compression Library (DCL) for Windows® provides a high-speed interface for compressing and decompressing data files within applications, when ZIP file archiving is not required. DCL compression generally reduces typical data file sizes by 50% or more, while reducing some types of ASCII and database files by as much as 90%.

PKWARE’s well-known DCL has been available for over a decade with the traditional DCL Implode compression algorithm. With this new release, the Windows DCL now includes support for the DEFLATE and DEFLATE64 algorithms. Moreover, this release expands the number of exposed functions significantly, providing more options and greater control. There are no limits to the types of data that can be processed with the PKWARE DCL algorithms, allowing compression and decompression to and from memory, media, serial ports, or any other device that an application can address.

DCL features include:

• Availability for Windows 32-bit platforms as both static and dynamic link libraries.
• Best of breed data compression algorithms including: DCL IMPLODE, DEFLATE, and DEFLATE64.
• Highly optimized code and C interface for superior performance.
• Adjustable dictionary size that allows software fine-tuning for maximum speed or compression efficiency.
• Use of application-defined callback or compression streaming functions allows for maximum flexibility.
• CRC-32 calculation routine for data integrity verification.

SecureZIP Toolkit for Windows®

The SecureZIP Toolkit for Windows includes all the capabilities of the PKZIP® Toolkit for Windows with the addition of strong data security functionality.

The SecureZIP Toolkit for Windows allows Windows applications to leverage Microsoft’s Crypto API , enabling applications to encrypt files using a wide range of industry and government standard symmetric key algorithms including 3DES and AES. Files can be encrypted using either passphrases or X.509-compliant digital certificates, providing the flexibility to work within different security environments. Digital signature capabilities are also available to help ensure file authenticity, integrity, and to support non-repudiation. Additionally, support for LDAP-compliant interfaces allows for the automatic location and retrieval of X.509 certificates for data encryption.

SecureZIP Toolkit for Windows includes a number of enhancements to enable more flexibility and efficiency for applications:

• Filename encryption enables the encryption of filenames and other file meta data to ensure no sensitive information is exposed.
• Support for LDAP-compliant directories allows for automatic retrieval and application of digital certificates for encryption.
• Shred files using DOD 5220 standard, providing an additional level of configurability for organizations that want to ensure that deleted files are not recoverable.

SecureZIP Toolkit for Windows features include:

• All the compression, decompression, and archive management capabilities of the PKZIP Toolkit for Windows.
• Available for Windows 32-bit and 64-bit platforms as dynamic link libraries.
• Create self-extracting ZIP files that allow files to be automatically unzipped and extracted.
• X.509 digital certificate support for encryption and digital signatures.
• Available encryption methods include: AES (128-, 192-, and 256-bit), 3DES (168-bit),SHA-256, SHA-384, and SHA-512.
• Decryption methods include: AES (128-, 192-, and 256-bit), 3DES (112- and 168-bit), DES (56-bit), RC2 (40-, 60-, and 128-bit), and RC4 (40-, 60-, and 128-bit).
• C/C++ object interface, combining easy integration with high performance.
