usage: in-toto-verify <named arguments> [options]

in-toto-verify is the main verification tool of the suite, and it is used to
verify that the software supply chain of the delivered product was carried out
as defined in the passed in-toto supply chain layout. Evidence for supply chain
steps must be available in the form of link metadata files named
'<step name>.<functionary keyid prefix>.link'.

Both 'in-toto-run' and 'in-toto-record' generate link metadata named in this
manner. If you require special handling of the in-toto link metadata files,
please take a look at the library api to modify this behavior.

The verification includes the following checks:
  * the layout is signed with the passed keys,
  * the layout has not expired,
  * a threshold of link metadata files exists for each step of the layout,
  * link files are signed by the authorized functionaries,
  * the materials and products for each step, as reported by the corresponding
    link files, adhere to the artifact rules specified by the step.

Additionally, inspection commands defined in the layout are executed
sequentially, followed by processing the inspections' artifact rules.

If the layout includes sublayouts, the verification routine will recurse into a
subdirectory named '<step name>.<keyid prefix>', where all the links relevant
to that sublayout must exist. The sublayout itself must be in the same
directory as the other links of the superlayout. (i.e. '<step name>.<keyid
prefix>.link')

The verification workflow is performed in isolation and does not rely on
information about keys that are available through external sources. For example,
in-toto does not rely on the creation time, revocation status, and usage flags
for PGP keys.

The command returns 2 if it is called with wrong arguments, 1 if in-toto
verification fails and 0 if verification passes.

Required Named Arguments:
  -l <path>, --layout <path>
                        path to root layout specifying the software supply chain to be verified.
  -k <path> [<path> ...], --layout-keys <path> [<path> ...]
                        paths to public key files used to verify the passed root layout's
                        signatures. See '--key-types' for available formats. Passing at least one
                        key using '--layout-keys' and/or '--gpg' is required. For each passed key
                        the layout must carry a valid signature.
  -g <id> [<id> ...], --gpg <id> [<id> ...]
                        GPG keyid, identifying a public key in the GPG keyring used to verify the
                        passed root layout's signatures. Passing at least one key using '--layout-
                        keys' and/or '--gpg' is required. For each passed key the layout must
                        carry a valid signature.

Options:
  -h, --help            show this help message and exit
  -t {rsa,ed25519,ecdsa} [{rsa,ed25519,ecdsa} ...], --key-types {rsa,ed25519,ecdsa} [{rsa,ed25519,ecdsa} ...]
                        types of keys specified by the '--layout-keys' option. 'rsa' keys are
                        expected in a 'PEM' format. 'ed25519' and 'ecdsa' are expected in a custom
                        'securesystemslib/json' format. If multiple keys are passed via '--layout-
                        keys' the same amount of key types must be passed. Key types are then
                        associated with keys by index. If '--key-types' is omitted, the default of
                        'rsa' is used for all keys.
  --link-dir <path>     path to directory from which link metadata files for steps defined in the
                        root layout should be loaded. If not passed, links are loaded from the
                        current working directory.
  --gpg-home <path>     path to a GPG home directory used to load a GPG key identified by '--gpg'.
                        If '--gpg-home' is not passed, the default GPG home directory is used.
  -v, --verbose         show more output
  -q, --quiet           suppress all output
  --version             show program's version number and exit

EXAMPLE USAGE

Verify supply chain in 'root.layout', signed with private part of
'key_file.pub'.

  in-toto-verify --layout root.layout --layout-keys key_file.pub

Verify supply chain as above but load links corresponding to steps of
'root.layout' from 'link_dir'.

  in-toto-verify --layout root.layout --layout-keys key_file.pub \
      --link-dir link_dir

Verify supply chain in 'root.layout', signed with GPG key '...7E0C8A17',
for which the public part can be found in the GPG keyring at '~/.gnupg'.

  in-toto-verify --layout root.layout \
      --gpg 8465A1E2E0FB2B40ADB2478E18FB3F537E0C8A17 \
      --gpg-home ~/.gnupg
