productsign(1) BSD General Commands Manual productsign(1)NAMEproductsign — Sign an OS X Installer product archive
SYNOPSISproductsign [options] --sign identity input-product-path
output-product-path
DESCRIPTIONproductsign adds a digital signature to a product archive previously cre‐
ated with productbuild(1). Although you can add a digital signature at
the time you run productbuild(1), you may wish to add a signature later,
once the product archive has been tested and is ready to deploy. If you
run productsign on a product archive that was previously signed, the
existing signature will be replaced.
To sign a product archive, you will need to have a certificate and corre‐
sponding 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.
productsign will embed the signing certificate in the product archive, as
well as any intermediate certificates that are found in the keychain. If
you need to embed additional certificates to form a chain of trust
between the signing certificate and a trusted root certificate on the
system, use the --cert option to give the Common Name of the intermediate
certificate. Multiple --cert options may be used to embed multiple inter‐
mediate certificates.
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 product ar‐
chive.
--keychain keychain-path
Specify a specific keychain to search for the signing iden‐
tity.
--cert certificate-name
Specify an intermediate certificate to be embedded in the
product archive.
--timestamp
Include a trusted timestamp with the signature.
--timestamp=none
Disable trusted timestamp, regardless of identity.
input-product-path
The product archive to be signed.
output-product-path
The path to which the signed product archive will be writ‐
