SQ(1) User Commands SQ(1) NAME sq-pki-authenticate - Authenticate a binding SYNOPSIS sq pki authenticate [OPTIONS] DESCRIPTION Authenticate a binding. Authenticate a binding (a certificate and User ID) by looking for a path from the trust roots to the specified binding in the Web of Trust. Because certifications may express uncertainty (i.e., certifications may be marked as conveying only partial or marginal trust), multiple paths may be needed. An error is return if no binding could be authenticated to the speci- fied level (by default: fully authenticated, i.e., a trust amount of 120). If any valid paths to the binding are found, they are printed on stdout whether they are sufficient to authenticate the binding or not. 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. --email=EMAIL Authenticate the specified email address This checks whether it is possible to authenticate a user ID with the specified email address. The user IDs do not need to be self signed. To authenticate a user ID containing just the specified email address, use `--userid <EMAIL>`. --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 au- thenticate a certificate. For instance, imagine Ed wants to au- thenticate Laura's certificate, but asking her directly is in- convenient. Ed discovers that Micah has certified Laura's cer- tificate, 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, be- cause 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. --userid=USERID Authenticate the specified user ID The specified user ID does not need to be self signed. Global options See sq(1) for a description of the global options. EXAMPLES Authenticate a specific binding. sq pki authenticate --cert \ EB28F26E2739A4870ECC47726F0073F60FD0CBF0 --userid \ "Alice <alice@example.org>" Check whether we can authenticate any user ID with the specified email address for the given certificate. sq pki authenticate --cert \ EB28F26E2739A4870ECC47726F0073F60FD0CBF0 --email \ alice@example.org SEE ALSO sq(1), sq-pki(1).
