PKZIP® for desktop - Feature Benefits
ZIP archives that reduce file size by as much as 95%
Experience bottom-line cost reductions from conservation of bandwidth, storage space, and backup tapes.

Large file size support
PKZIP can compress files of over 9 exabytes in size.

Very large archive support
Over 2 billion files can be included in a single ZIP archive.

Strong password-based data file protection
PKZIP supports AES or 3DES encryption to protect valuable information. Files encrypted with PKZIP may be decrypted and extracted on major enterprise computing platforms using PKZIP or SecureZIP®.

Decryption of PKI public-key encrypted ZIP archives
PKZIP users can decrypt and extract files encrypted with a PKI public key by SecureZIP products.

Authentication of digitally signed archives and files
Recipients of digitally signed files can validate the signature to ensure the sender is who he or she claims to be, and verify that files have not been altered or tampered with since signed.

Command-line add-on for automating recurring tasks
PKZIP provides a command-line interface allowing users to create scripts for automating unattended script and batch processing.

Seamless integration with Microsoft Outlook®
Compressing data is as easy as attaching files to email with PKZIP Outlook integration, making user training virtually unnecessary.

Configurable minimum passphrase length
Good passphrases are essential to maintaining the security of your data - the longer the passphrase, the more secure it is. PKZIP allows administrators to configure the minimum length of passphrases created by users.

Certificate revocation list checking
PKZIP can check the validity of digital certificates used to encrypt or digitally sign files against a Certificate Revocation List (CRL). When a PKZIP user receives a file that was signed or encrypted using SecureZIP, CRL checking will show a certificate that has been revoked as invalid.

Administrative lockdown of end-user options
PKZIP is the only ZIP utility with a Policy Manager to lock configuration options, so that compression practices can be enforced for individuals or departments — delivering considerable bottom-line savings from consistent, company-wide data compression.
