NAME
       sq pki vouch add - Certify a User ID for a Certificate

SYNOPSIS
       sq pki vouch add [OPTIONS]

DESCRIPTION
       Certify a User ID for a Certificate.

       Using a certification a keyholder may vouch for the fact that another
       certificate legitimately belongs to a user id.  In the context of
       emails this means that the same entity controls the key and the email
       address.  These kind of certifications form the basis for the Web of
       Trust.

       This command emits the certificate with the new certification.  The
       updated certificate has to be distributed, preferably by sending it to
       the certificate holder for approval.  See also `sq key approvals`.

       By default a certification expires after 10 years. Using the
       `--expiration` argument specific validity periods may be defined. It
       allows for providing a point in time for validity to end or a validity
       duration.

       `sq pki vouch add` respects the reference time set by the top-level
       `--time` argument.  It sets the certification's creation time to the
       reference time.



OPTIONS
   Subcommand options
       --add-email=EMAIL
              Use a user ID with the specified email address

              The user ID consists of just the email address.  The email
              address does not have to appear in a self-signed user ID.

       --add-userid=USERID
              Use the specified user ID

              The specified user ID does not need to be self signed.

              Because using a user ID that is not self-signed is often a
              mistake, you need to use this option to explicitly opt in.

       --all  Use all self-signed user IDs

       --allow-non-canonical-userids
              Don't reject new user IDs that are not in canonical form

              Canonical user IDs are of the form `Name (Comment)
              <localpart@example.org>`.

       --amount=AMOUNT
              Set the amount of trust

              Values between 1 and 120 are meaningful.  120 means fully
              trusted.  Values less than 120 indicate the degree of trust.  60
              is usually used for partially trusted.

              [default: full]

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

       --cert-file=PATH
              Read certificates from PATH

       --certifier=FINGERPRINT|KEYID
              Create the certification using the key with the specified
              fingerprint or key ID

       --certifier-email=EMAIL
              Create the certification using the key where a user ID includes
              the specified email address

       --certifier-file=PATH
              Create the certification using the key read from PATH

       --certifier-self
              Create the certification using your default certification key

              This uses the certificates set in the configuration file under
              `pki.vouch.certifier-self` as certification key.

              Currently, there is no default certification key.


       --certifier-userid=USERID
              Create the certification using the key with the specified user
              ID

       --email=EMAIL
              Use a user ID consisting of just the email address, if the email
              address occurs in a self-signed user ID

       --expiration=EXPIRATION
              Sets the expiration time

              EXPIRATION is either an ISO 8601 formatted date with an optional
              time or a custom duration.  A duration takes the form
              `N[ymwds]`, where the letters stand for years, months, weeks,
              days, and seconds, respectively. Alternatively, the keyword
              `never` does not set an expiration time.

              The default can be changed in the configuration file using the
              setting `pki.vouch.expiration`.

              [default: 10y]

       --local
              Make the certification a local certification

              Normally, local certifications are not exported.

       --non-revocable
              Mark the certification as being non-revocable

              That is, you cannot later revoke this certification.  This
              should normally only be used with an expiration.

       --output=FILE
              Write to FILE or stdout if omitted

       --signature-notation NAME VALUE
              Add a notation to the signature

              A user-defined notation's name must be of the form
              `name@a.domain.you.control.org`. If the notation's name starts
              with a `!`, then the notation is marked as being critical.  If a
              consumer of a signature doesn't understand a critical notation,
              then it will ignore the signature.  The notation is marked as
              being human readable.

       --userid=USERID
              Use the specified self-signed user ID

              The specified user ID must be self signed.

       --userid-by-email=EMAIL
              Use the self-signed user ID with the specified email address

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