sign.sh adds lines to a manifest to indicate the approval
|
|
|
|
|
of the integrity of the firmware as required for automated
|
|
|
|
|
updates. The first argument <secret> references a file harboring
|
|
|
|
|
the private key of a public-private key pair of a developer
|
|
|
|
|
that referenced by its public key in the site configuration.
|
|
|
|
|
The script may be performed multiple times to the same document
|
|
|
|
|
to indicate an approval by multiple developers.
