In addition, the processing load of encrypting all that junk mail might hamper or even destroy the economics and operational models of botnet-based spam and virus operations.īut encryption technology is not readily available nor is it generally inexpensive, except to enterprise users that buy large-scale, server-based encryption systems. After all, if people only read encrypted mail, they’d never open a spam or a virus-carrying message or attachment. The simplest way to secure e-mail may be to encrypt all messages.

Example2: if outside.zip contains inside.tar, the data in the temp file is NOT encrypted, as TAR doesnt allow for encryption.Creating streamed archives: When you write an archive to a data streamfor example, to STDOUT (see chapter 3 of the Users Manual for the Server or Command Line productsPKZIP compresses and (if encryption is specified) encrypts the data before writing it to the temporary file. Example1: if outside.zip contains inside.zip, the data in the temporary file is encrypted only if it was encrypted in inside.zip. The data in the temporary file is encrypted only if the archive is encrypted. In this case, the embedded archive is extracted into a temporary file before its files are extracted.
