Ubuntu Manpage: sq-pki-identify - Identify a certificate

NAME

       sq-pki-identify - Identify a certificate

SYNOPSIS

       sq pki identify [OPTIONS]

DESCRIPTION

       Identify a certificate.

       Identify a certificate by finding authenticated bindings (User ID and certificate pairs).

       An  error  is  return  if  no  binding  could  be authenticated to the specified level (by default: fully
       authenticated, i.e., a trust amount of 120).

       If a binding could be partially authenticated (i.e., its trust  amount  is  greater  than  0),  then  the
       binding is displayed, even if the trust is below the specified threshold.

OPTIONS

Subcommand options
--amount=AMOUNT
The required amount of trust

120 indicates full authentication; values less than 120 indicate partial authentication. When
`--certification-network` is passed, this defaults to 1200, i.e., this command tries to find 10
paths.

--cert=FINGERPRINT|KEYID
Use certificates with the specified fingerprint or key ID

--certification-network
Treats the network as a certification network

Normally, the authentication machinery treats the Web of Trust network as an authentication
network where a certification only means that the binding is correct, not that the target should
be treated as a trusted introducer. In a certification network, the targets of certifications are
treated as trusted introducers with infinite depth, and any regular expressions are ignored.
Note: The trust amount remains unchanged. This is how most so-called PGP path-finding algorithms
work.

--gossip
Treats all certificates as unreliable trust roots

This option is useful for figuring out what others think about a certificate (i.e., gossip or
hearsay). In other words, this finds arbitrary paths to a particular certificate.

Gossip is useful in helping to identify alternative ways to authenticate a certificate. For
instance, imagine Ed wants to authenticate Laura's certificate, but asking her directly is
inconvenient. Ed discovers that Micah has certified Laura's certificate, but Ed hasn't yet
authenticated Micah's certificate. If Ed is willing to rely on Micah as a trusted introducer, and
authenticating Micah's certificate is easier than authenticating Laura's certificate, then Ed has
learned about an easier way to authenticate Laura's certificate.

Stable since 1.1.0.

--show-paths
Show why a binding is authenticated

By default, only a user ID and certificate binding's degree of authentication (a value between 0
and 120) is shown. This changes the output to also show how that value was computed by showing
the paths from the trust roots to the bindings.

--unusable
Show bindings that are unusable

Normally, unusable certificates and bindings are not shown. This option considers bindings, even
if they are not unusable, because they (or the certificates) are not valid according to the
policy, are revoked, or are not live.

This option only makes sense with `--gossip`, because unusable bindings are still considered
unauthenticated.

Stable since 1.1.0.

EXAMPLES

       Identify the user IDs that can be authenticated for the certificate.

              sq pki identify --cert \
                     EB28F26E2739A4870ECC47726F0073F60FD0CBF0

       List all user IDs that have that have been certified by anyone.

              sq pki identify --gossip --cert \
                     511257EBBF077B7AEDAE5D093F68CB84CE537C9A
