![]() Where GPG gives you a bicycle, OpenSSL gives you some metal rods of various sizes and a couple of rubber chambers (screws and pump not included). Although you can do some things with it (in particular, it does have all the primitives needed for a basic certification authority), it's hard to use correctly and it doesn't have all you need to do things right. This article explains how to use the tar command to extract (or unzip). ![]() By convention, the name of a tar archive compressed with xz ends with either. It's a showcase for the OpenSSL library, not designed for production use. Xz is a popular algorithm for compressing files based on the LZMA algorithm. It's less secure because the only security is the password, whereas key-based encryption splits the security between the password and the key.ĭon't use the openssl command line tool. xz is a general-purpose data compression tool with command line syntax similar to gzip and bzip2. As you can see, file1.txt has now become. The xz command in its simplest form, used to compress a single file with default options. ![]() scripts/xzwrap.sh is a wrapper for the xz command line tool found from XZ Utils. Heres how to extract GZ files on Linux using a graphical interface: Using your preferred file manager, navigate to the folder where the. It's less flexible because you need to specify the password when encrypting (so for example you can't make unattended backups). The simplest way to create an xz archive is by invoking the xz command and specifying the name of the file you wish to compress. c files, which is defined in include/linux/decompress/generic.h. GPG also lets you encrypt a file with a password. To decrypt a file, you'll need to enter the passphrase to unlock your private key. Encrypt your files, specifying your email as the recipient. If you are under windows you can use 7zip. and then use this command to decompress your file: unxz ubuntu-19.10-preinstalled-server-arm64+. To be able to decompress it from the command line you need to install xz-utils: sudo apt-get install xz-utils. Create a key and associate it with your email address (GPG/PGP key identifiers usually contain an email address, though it is not necessary ). xz is a compression format like zip or gz. Many tar implementation, including GNU tar (the normal implementation on Linux), can automatically compress with an option ( -z for gzip, -j for bzip2, -J for xz): tar -cJf file1 file2 file3 tar -xJf node-v18.7.0-linux-圆4.tar.xz (file extracts) Just don't specify a format and let tar detect the compression automatically: tar -xf node-v18.7.0-linux-圆4.tar. If you have images on a disk (which is most often the case), you must use this as your source. Only a tool called 7zip can extract tars from Windows. By using the xz command, you can compress a file. There are separate tools such as gzip, bzip2 and xz (in increasing order of compression ratio on typical files) that compress one file. Answering my own question to help others: tar (at least GNU tar) already handles this compression format, you can either: Use '-J' to tell tar to expect XZ. To extract an img.xz file in Linux, you will need to use a terminal and the xz command.
