How to use OpenPGP.

Our keys are made to work with OpenPGP, an open asymmetric encryption standard. OpenPGP is available on a number of apps, but we recommend either the following apps:

GnuPG¹ command-line utility
Gpg4win² for Windows
GPG Suite² for macOS
Kleopatra² for Linux (also bundled in Gpg4win)
OpenKeychain² for Android
PGPro³ for iOS and iPadOS

¹GPG or GnuPG stands for GNU Privacy Guard, an open-source implementation for OpenPGP. Some command-line tutorials on OpenPGP introduces the gpg command which are specific to GnuPG, not OpenPGP.

²Recommended for use in Git.

³Importing and use of subkeys are not possible due to the limitations of the cryptographic processing library.

Digitally sign Git commits

Use Git and GnuPG to sign your commits. Tell Git and your Git hosting your hosting provider.

Official guides are available for Codeberg (Forgejo), Gitee, GitHub, and GitLab.

Certain apps including JetBrains IDE also have built-in GPG signing support.
