The documentation for the certutil tool [1] refers to a "u" value for

It seems that the certutil man page should be improved to document
the "u" trust attribute as "user cert: the private key associated with
the certificate exists and can be used for authentication, signing, or
decryption."

But, no matter how I import a certificate, I can't get "signtool -l" to
list that as one that I can sign things with.  It will list a testing
cert made with "signtool -G" and then "certutil -L" says "u,u,Cu" for
that testing cert, but the same permission on import of a real cert
produces "G,,C".

Is "G" a valid trust attribute?  It's not documented in the certutil man page
http://www.mozilla.org/projects/security/pki/nss/tools/certutil.html#1034193.

So.  Is there something special about certs that can be used to sign
objects?

I hope you're using "certs" as an informal shorthand for "certs or the
associated private keys".  It's the private keys that can be used to sign
objects.
