Traditionally, Linux users use the Adobe Acrobat Reader to sign PDF documents, but it is no longer supported on the Linux operating system. There are several open-source PDF readers, including GNU/Linux’s Xournal, which have limited editing capabilities and do not allow adding signatures. However, you can sign a PDF using GNU/Linux by using Xournal.
One way to use Xournal to sign a PDF on Linux is to capture your signature using your webcam or your smartphone camera. You may need to tweak the image so it is transparent. To do so, make sure the background is white. If you have a webcam, you can take a screenshot of the image. If you want the signature to be transparent, you can add a white background to it.
Alternatively, you can use the uPdf tool to sign a PDF. To add a signature, click on the ‘Add an image’ tool in uPdf. Then, select the image file you wish to add. PNG images with a transparent background are the best choice. Once you’ve added your signature, you can export it to a PDF. And, that’s it!

What is Signature in Linux?
What is Signature in Linux? A signature is a digital file used to verify the integrity of a document. This is important because software packages can be intercepted in transmission, and the files inside them can be altered. To prevent this from happening, software packages from reputable Linux and GNU projects are digitally signed. Digital signatures also provide the user with information such as the modification digest of a file. Digital signatures may be included with a package file, or posted separately. To verify a digital signature, simply run the gpg command.
A signed module has a public key that is not stored in the ELF container. It also may not be stripped after the signature computation is complete. It includes all debug information. Signed modules are loaded using insmod, modprobe, and init_module(). The kernel performs signature checking during the loading process, and can be a security measure to keep your operating system secure. In fact, many malwares can compromise your system if you leave your private key in the root node.
