  1. 7-Zip 21.0 alpha introduces native Linux support Each year, the free archiver 7-Zip gets updated to a new version. The developer of the application has released two alpha previews of this year's 7-Zip 21 version. Reason enough to take a look at the new version of 7-Zip and the changes and improvements compared to the previous versions of the file archiver. The latest alpha release is available on the 7-Zip project site. Just download the 32-bit, 64-bit or 64-bit ARM64 version of the program from the site and run the installer after the download. One of the main changes, introduced in the second alpha release, 7-Zip 21.01, is that a command line version of 7-Zip for Linux has been released. The release is not included in the main packages for Windows; the download site lists two downloads for the command line version for Linux that are for 32-bit/64-bit and 64-bit ARM Linux devices. A readme file is included that explains core functionality of the command line version. The Linux version includes all changes from the latest 7-Zip version for Windows. The full changelog is relatively short. The first alpha version, released in January 2021, made internal code changes, fixed several unspecified bugs, and added Tajik and Uzbek localizations. The latest release, 7-Zip 21.01 alpha, released on March 9, 2021, includes several improvements. Next to the Linux command line version, it is addressing a long-standing bug in 7-Zip that dates back to version 18.02. Previous versions of 7-Zip had sometimes issue extracting ZIP archives with xz compression; this bug is fixed in the latest alpha release of 7-Zip and will find its way into the next stable release of the application as well. Speed of the ARM64 version of 7-Zip has been improved in the release according to the release notes. Last but not least, several bugs were fixed that were not mentioned specifically. The alpha version ran stable and without issues on the test system; most users may want to wait until the final version is released. Those on Linux may give the new command line version a go on the other hand. Now You: which file archiver do you use? (via Deskmodder) Source: 7-Zip 21.0 alpha introduces native Linux support

  3. How To Use 7-Zip To Encrypt Files If you need strong command line encryption on Linux, look no further than 7zip You have information on your machines that needs to be secure. This could be client data, company secrets, or your own personal information that you don't want viewed by the wrong person. To that end, you'll go to some rather challenging means to protect that information. But what if that task could be made considerably easier? Although some might not think of the command line as the easier option, there are some CLI tools that do make short shrift of a task. Such is the case with 7zip. Although this tool is typically used for zipping and unzipping files, it also includes the ability to encrypt and decrypt those files. I want to walk you through the installation and usage of 7zip for file encryption. I'll be demonstrating on Ubuntu Server, but the tool can be used on most Linux distributions. What you'll need A running Linux distribution A user with sudo privileges Some data to encrypt How to install the 7zip package on Linux distributions Chances are slim your Linux distribution includes the 7zip package. In order to install the package that includes the encryption features, log in to your Linux machine, open a terminal window, and issue the following command: sudo apt-get install p7zip-full -y To install on a different type of distribution, use a similar command as shown above, substituting apt-get for the likes of dnf or zypper. That's all there is to the installation. How to encrypt files with 7zip Let's say you have the file webservers, which contains important information about the web servers in your data center. To encrypt that file with 7zip, issue the command: 7z a -p -mx=9 -mhe -t7z webservers.7z webservers The options used above are: a: Add files to archive -p: Prompt for a password -mx=9: Level of compression (9 being ultra) -mhe: Encrypt file names -t7z: Generate a 7z archive You will be prompted to create a passphrase for the encryption. Once you've done that, the new encrypted file webservers.7z is created. You can also encrypt multiple files. Say you have the files webservers and kubernetes to be encrypted into the file data.7z. The command for this would be: 7z a -p -mx=9 -mhe -t7z data.7z webservers kubernetes the above command would create the encrypted data.7z file, encrypted by the password of your choice. Once you've encrypted the files, you should then delete the originals. Why? Because those original files (in our examples webservers and kubernetes) aren't encrypted. Only the newly created .7z files are encrypted. So delete those files with the command: rm webservers kubernetes How to decrypt files with 7zip Those files wouldn't be of any use to you if you couldn't decrypt them. So how do you do that? We have the files data.7z and webservers.7z. With 7z, file decryption is done like so: 7za e data.7z or 7za e webservers.7z In either instance, you'll be asked for the passphrase you created during the encryption process. If you failed to delete the original files (which you shouldn't neglect to do), 7z will ask if you want to overwrite the existing files--in our examples that would be webservers and kubernetes (Figure A). Figure A Once you've decrypted the file(s), you can then view their contents. And that's the gist of using 7zip to encrypt and decrypt files. For anyone who needs strong command line encryption on Linux, this might well be the ideal choice for you. Source
