Zip files are generally used to locally back up groups of files that might be undergoing changes or to copy files to other systems one group at a time. Similarly, the zipcloak -d (decrypt) command will decrypt an encrypted zip file whether it was encrypted with a zip -e command or a zipcloak command. The unzip command can extract content from unencrypted and encrypted zip files and works as expected whether the files were encrypted with a zip -e (encrypt) command or a zipcloak command. The zip and zipcloak commands are properly compatible. Here is an example of both extracting a single file and electing to overwrite the current file: $ unzip efiles.zip file2

In addition, you can select individual files from a zip file if you don’t want to extract all of them. If files by the same names exist in the directory, you will be asked whether you want to overwrite them. It will, however, ask for the password for encrypted files. The unzip command will extract the contents of zip files whether they are encrypted or not. 1 shs shs 3961 Nov 19 14:30 files.zipĪfter the encryption, resultant file is nearly identical in size to the one created without encryption. To use the zipcloak command to encrypt a zip file, use a command like the one shown below. The zipcloak command is different from zip in one very important way: It will encrypt or decrypt an existing zip file, but it will not create a zip file on its own. NOTE: Zip files are smaller than the collection of separate files included in them whether or not they are encrypted. For that, you can use the zipcloak command or go through the process of extracting the zip file’s contents and then re-zipping them using the -e option to put them back together in encrypted form. While the zip command can create encrypted files, it cannot encrypt existing zip files. Here’s an example command that would put all of the files in your bin directory into a file named “bin.zip”. You can also use the zip command to recursively collect files and include them in a single zip file. The original files, after being added to the encrypted zip file, can be deleted afterwards, but you will need to preserve the password used so that you can extract the contents later.

The zip file in these examples is less than half the size of the two files combined. The zip command not only stores the files together, but reduces the size of the files in the process.
