GpgFrontend

GpgFrontend is a Free, Open Source, Powerful, Easy-to-Use, Compact, Cross-Platform OpenPGP Crypt Tool. Also, it's one of the excellent GUI Frontends for Modern GnuPG (gpg).

By using GpgFrontend,

• You can quickly make encrypted files or texts.
• You can digitally sign your texts or files.
• You can easily manage all your GPG keys on your machine.
• You can easily and safely transfer all your GPG keys between your machines.
• Furthermore, you can build and run it on Windows, macOS, Linux, FreeBSD, etc.

GpgFrontend is PERMANENTLY FREE, but you can also "DONATE" it through STAR this project. Thanks!

Languages Supported by GpgFrontend including English, Chinese, French, Russian, German, Spanish, Portuguese, Arabic, etc.

Usage

Here are some common usages to help you understand what GpgFrontend does. The interface presented here may not be exactly the same as the latest stable release.

Text Encryption & Decryption

Encryption can be done in just a few clicks.

Paste the text, and just click decryption.

File Encryption & Sign

What about files?

User Manual

GpgFrontend provides documentations on its main features. If you want to know how to install, please read the User Manual instead of README.

Build From Source Code

For some experts, building GpgFrontend from source code is a good option. I encourage people to freely build, package and distribute their own versions. The method I build in major operating systems is as follows:

Note: "$" Symbols indicate commands to should be executed with a normal user.

$ git clone --recurse-submodules https://github.com/saturneric/GpgFrontend.git

For Windows

Before building, you need to install MSYS2. After installation, open the MSYS2 terminal (MSYS2 MinGW 64-bit), enter the MSYS2 directory, and execute the following commands:

pacman --noconfirm -S --needed mingw-w64-x86_64-gcc mingw-w64-x86_64-make mingw-w64-x86_64-cmake autoconf
pacman --noconfirm -S --needed make texinfo mingw-w64-x86_64-libconfig mingw-w64-x86_64-boost automake
pacman --noconfirm -S --needed mingw-w64-x86_64-qt5 libintl msys2-runtime-devel gettext-devel mingw-w64-x86_64-gpgme
pacman --noconfirm -S --needed mingw-w64-x86_64-ninja mingw-w64-x86_64-gnupg mingw-w64-x86_64-libarchive

After executing these commands, you will start compiling.

$ cd GpgFrontend
$ mkdir build && cd build
$ cmake -G Ninja  -DCMAKE_BUILD_TYPE="Release" ..
$ ninja

After compiling, a release directory will be generated, which contains executable files that can be run directly.

$ ./release/GpgFrontend.exe

For macOS

Install and compile dependencies.

$ brew install cmake git autoconf automake qt@5 texinfo gettext [email protected] libarchive
$ brew install boost ninja
$ brew unlink gettext && brew link --force gettext
$ brew link qt@5

Build the code separately for debug.

$ cd GpgFrontend
$ mkdir build && cd build
$ cmake -G Ninja  -DCMAKE_BUILD_TYPE="Debug" -DOPENSSL_ROOT_DIR=/usr/local/opt/[email protected]  ..
$ ninja
$ ./release/GpgFrontend # run the program

Build the code and make the App Bundle.

$ cd GpgFrontend
$ mkdir build && cd build
$ cmake -G Ninja  -DCMAKE_BUILD_TYPE="Release" -DOPENSSL_ROOT_DIR=/usr/local/opt/[email protected] ..
$ ninja
$ macdeployqt ./release/GpgFrontend.app

For Ubuntu 18.04 And Later

Install and compile dependencies.

$ sudo apt-get update
$ sudo apt-get -y install build-essential binutils git autoconf automake gettext texinfo
$ sudo apt-get -y install gcc-8 g++-8 ninja-build
$ sudo apt-get -y install libconfig++-dev libboost-all-dev libarchive-dev libssl-dev
$ sudo apt-get -y install gpg # If you need to run directly after building.

Compile and install libgpg-error/libassuan/gpgme. Notice: These component's version in third_party directory is newer than those in apt.

# libgpg-error
$ cd GpgFrontend
$ cd  ./third_party/libgpg-error
$ ./autogen.sh
$ ./configure --enable-maintainer-mode && make
$ sudo make install
# libassuan
$ cd GpgFrontend
$ cd  ./third_party/libassuan
$ ./autogen.sh
$ ./configure --enable-maintainer-mode && make
$ sudo make install
# gpgme
$ cd GpgFrontend
$ cd  ./third_party/gpgme
$ ./autogen.sh
$ ./configure --enable-maintainer-mode --enable-languages=cpp && make
$ sudo make install

Build the code and make the deb package(Please use Ubuntu 20.04 or later).

$ cd GpgFrontend
$ mkdir build && cd build
$ cmake -G Ninja  -DCMAKE_BUILD_TYPE="Release" -DGPGFRONTEND_GENERATE_LINUX_INSTALL_SOFTWARE=ON ..
$ ninja
$ ninja package

Build the code separately for debug(Please use ubuntu 18.04 or later).

$ cd GpgFrontend
$ mkdir build && cd build
$ cmake -G Ninja  -DCMAKE_BUILD_TYPE="Debug" ..
$ ninja
$ ./release/GpgFrontend # run the program

Package the AppImage(Should use ubuntu 18.04).

$ cd GpgFrontend
$ mkdir build && cd build
$ cmake -G Ninja  -DCMAKE_BUILD_TYPE="Release" ..
$ ninja
$ mkdir ./AppImageOut
$ cd ./AppImageOut
$ wget -c -nv https://github.com/probonopd/linuxdeployqt/releases/download/continuous/linuxdeployqt-continuous-x86_64.AppImage
$ chmod u+x linuxdeployqt-continuous-x86_64.AppImage
$ ./linuxdeployqt-continuous-x86_64.AppImage ../release/gpgfrontend/usr/share/applications/*.desktop -appimage
