System Requirement
These are the recommended requirements for running GpgFrontend. They are not strict; the app may run fine on weaker machines too.
Hardware
Section titled “Hardware”For smooth operation, we recommend:
- RAM: 2 GB or more
- Disk: 200 MB free for the app itself, plus space for GnuPG and your data
- CPU: a dual-core processor or better
- Windows 10 or later. Windows 7 can only run the older v2.1.x line, which still has Qt5 builds. It is not recommended.
- macOS 15 or later, on both Intel and Apple Silicon
- Linux on x86_64: Ubuntu 22.04 or later, or a comparable distribution
- Linux on arm64: Ubuntu 24.04 or later, or a comparable distribution
Note: Only 64-bit machines are supported.
- Minimum 2.2.0. Some features need newer versions than 2.2.0.
- GnuPG older than 2.1.0 is not used at all. GpgFrontend still starts, but it uses the built-in rPGP engine instead.
- Recommended: 2.4.0 or later.
- On Windows, the official packages already include a recent GnuPG, so there is nothing extra to install.
Since v2.2, the app also ships a second, built-in engine (rPGP). If GnuPG is missing or too old, the app still starts and works through rPGP, but the features that depend on GnuPG, such as smart cards, stay unavailable until a working GnuPG is found.
Optional on Linux
Section titled “Optional on Linux”To let GpgFrontend keep its own key in your system password store, you need a password service running, such as GNOME Keyring or KWallet, plus the libsecret library:
- Debian and Ubuntu:
libsecret-1-0 - Fedora:
libsecret
Without these, that option is greyed out in the settings. Everything else works as normal. See Application Secure Key.
Network
Section titled “Network”GpgFrontend works without the Internet. You only need a connection for optional things, such as update checks, key servers, or sending and reading email.
