PEM encoded keys, detached signatures in PEM/SMIME format.

verify-code (short cut for setting -u code)

which do the obvious.

See the second comment in nbsvtool.c.

Additional certificates to include in the signature

The certificate itself.

The private key matching the certificate for sign operations.

Can't comment on that. Currently supported are ssl-server, ssl-client,
code and smime, others (SGC, OCSP, timestamp, DVCS) can be added easily.

cat'ed list of PEM encoded certificates that are considered trusted.

Create signature file "hello.sp7" for file "hello". Private key is found
in file "key", certificates from "cert-chain" are included. The
certificate matching the private key must be included.

Verify that the signature "hello.sp7" for file "hello" is valid and that
the certificate allows code signing.

Same but check "file" instead.

Check signature "file.sp7" of "file", using "anchor-file" as trust
