Description:
GnuPG keys of Debian Developers and Maintainers
The Debian project wants developers to digitally sign the announcements of their packages with GnuPG, to protect against forgeries. This package contains keyrings of GnuPG and keys of Debian Developers (uploading and non-uploading), as well as of Debian Maintainers. . Do note that, although this package is provided for convenience, it is not necessarily kept updated with the latest changes; the authoritative source for keyring information is publicly accessible via rsync at: . keyring.debian.org::keyrings/keyrings/ . Finally, the following Git repository is usually kept up to date with the public authoritative data: . https://salsa.debian.org/debian-keyring/keyring.git
