GPG file format is used files created with GNU Privacy Guard (GnuPG), a file encryption tool. GPG filecontains public security keys and encrypted tokens.
Security keys stored in GPG files use OpenPGP standard defined by RFC2440, the same standard the PGP (Pretty Good Privacy) format uses. GPG security keys are used for decrypting files encrypted with GNU Privacy Guard.
The list that follows enumerates programs compatible with GPG files, divided into 3 categories based on operating system on which they are available. Files with GPG suffix can be copied to any mobile device or system platform, but it may not be possible to open them properly on target system.
There can be multiple causes why you have problems with opening GPG files on given system. Fortunately, most common problems with GPG files can be solved without in-depth IT knowledge, and most importantly, in a matter of minutes. The list below will guide you through the process of addressing the encountered problem.
The most common reason for such problems is the lack of proper applications that supports GPG files installed on the system. The solution is straightforward, just download and install GnuPG. The full list of programs grouped by operating systems can be found above. The safest method of downloading GnuPG installed is by going to developer’s website () and downloading the software using provided links.
If you already have GnuPG installed on your systems and GPG files are still not opened properly, check if you have the latest version of the software. Software developers may implement support for more modern file formats in updated versions of their products. The reason that GnuPG cannot handle files with GPG may be that the software is outdated. All of the file formats that were handled just fine by the previous versions of given program should be also possible to open using GnuPG.
If you have the latest version of GnuPG installed and the problem persists, select it as the default program to be used to manage GPG on your device. The process of associating file formats with default application may differ in details depending on platform, but the basic procedure is very similar.
