usage: tuf add-signatures [--signatures <sig_file>] [--format=<format>] [--key-id=<key-id>] <metadata>
Adds signatures (the output of "sign-payload") to the given role metadata file.
If the signature does not verify, it will not be added.
Options:
--signatures=<sig_file> The path to the file containing the signatures to add. If not present, the contents are read from stdin
--format=<format> One of 'json', 'hex', or 'base64'. Defaults to 'json'
--key-id=<key-id> The key-id of the signature being added. Only required if the format is not 'json'
