SQ(1)

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., `sq pki` 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, `sq pki` 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.

--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.

  Global options
See sq(1) for a description of the global options.

EXAMPLES

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

    sq pki identify --cert \

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

    sq pki identify --gossip --cert \
