PKWare Encrypts Compressed Files
.Zip file format pioneer is enabling users of its compression software to also add authentication and encryption.PKWare Inc, the inventor of the .zip file format, is adding new security features to its compression technology. This week the company made available Version 5.0 of its PKZip data compression software, which also enables users to assign a password for authentication or a digital certificate for encryption. It supports x.509 version 3 digital certificates with Public Key Infrastructure in partnership with security vendors RSA, Entrust, VeriSign and Baltimore. Version 5.0 incorporates the Brown Deer, Wisc., companys 168-bit encryption algorithm. It can be integrated with Microsoft Corp.s Outlook 2000 e-mail client to provide automatic compression, digital signing and encryption of files., PKWare officials said.
In addition to reducing network bandwidth through compression, PKZIP 5.0 adds another level of security because it is more difficult for a hacker to crack open an encrypted file if it has been compressed, officials said.
