xip(1) BSD General Commands Manual xip(1)
NAME
xip -- Create a signed archive for secure distribution
SYNOPSIS
xip [options] --sign identity input-file ... output-archive
DESCRIPTION
The xip tool archives one or more files or directories into a signed XIP
file. A XIP file is an analog to zip(1), but allows for a digital signa-
ture to be applied and verified on the receiving system, before the ar-
chive is expanded. When a XIP file is opened (by double-clicking), Ar-
chive Utility will automatically expand it (but only if the digital sig-
nature is intact).
To create a XIP file, you will need to have a certificate and correspond-
ing private key -- together called an ``identity'' -- in one of your
accessible keychains. To add a signature, specify the name of the iden-
tity using the --sign option. The identity's name is the same as the
``Common Name'' of the certificate.
If you want to search for the identity in a specific keychain, specify
the path to the keychain file using the --keychain option. Otherwise, the
default keychain search path is used.
xip will embed the signing certificate in the XIP file, as well as any
intermediate certificates that are found in the keychain.
The signature can optionally include a trusted timestamp. This is enabled
by default when signing with a Developer ID identity, but it can be
enabled explicitly using the --timestamp option. A timestamp server must
be contacted to embed a trusted timestamp. If you aren't connected to the
Internet, you can use --timestamp=none to disable timestamps, even for a
Developer ID identity.
ARGUMENTS AND OPTIONS
--sign identity-name
The name of the identity to use for signing the archive.
--keychain keychain-path

tity.
--timestamp
Include a trusted timestamp with the signature.
--timestamp=none
Disable trusted timestamp, regardless of identity.
