## PGP key inclusion criteria
## PGP key policies
The qubes-secpack generally includes only those PGP keys used to sign some kind
of official project asset, such as Qubes release ISOs (release signing keys),
Git tags and commits (code signing, doc signing, and security team keys), and
the qubes-secpack's own files and Git tags (security team keys again). This
means that email keys are generally not included, even for official project
email addresses. There is one exception to this rule: the official [Qubes
security team](/security/#qubes-security-team) email address, which is used to
report security vulnerabilities in Qubes OS to our security team.
