NAME

       sq-pki-link-authorize - Make a certificate a trusted introducer

SYNOPSIS

       sq pki link authorize [OPTIONS]

DESCRIPTION

Make a certificate a trusted introducer.

This causes `sq` to consider the certificate to be a be a trusted introducer. Trusted introducer is
another word for certification authority (CA). When you link a trusted introducer, you consider
certifications made by the trusted introducer to be valid. A trusted introducer can also designate
further trusted introducers.

As is, a trusted introducer has a lot of power. This power can be limited in several ways.

- The ability to specify further introducers can be constrained using the `--depth` parameter.

- The degree to which an introducer is trusted can be changed using the `--amount` parameter.

- The user IDs that an introducer can certify can be constrained by domain using the `--domain`
parameter or a regular expression using the `--regex` parameter.

These mechanisms allow you to say that you are willing to rely on the CA for example.org, but only for
user IDs that have an email address for example.org, for instance.

A link can be retracted using `sq pki link retract`.

This command is similar to `sq pki vouch authorize`, but the certifications it makes are done using the
certificate directory's trust root, not an arbitrary key. Further, the certificates are marked as
non-exportable. The former makes it easier to manage certifications, especially when your certification
key is offline. And the latter improves your privacy, by reducing the chance that parts of your social
graph are leaked when a certificate is shared.

By default a link never expires. 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 link authorize` respects the reference time set by the top-level `--time` argument. It sets the
link'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-special=SPECIAL
Use certificates identified by the special name

[possible values: public-directories, keys.openpgp.org, keys.mailvelope.com, proton.me, wkd, dane,
autocrypt, web]

--depth=TRUST_DEPTH
Set the trust depth

This is sometimes referred to as the trust level. 1 means CERTIFICATE is a trusted introducer
(default), 2 means CERTIFICATE is a meta-trusted introducer and can authorize another trusted
introducer, etc.

[default: 255]

--domain=DOMAIN
Add a domain constraint to the introducer

Add a domain to constrain what certifications are respected. A certification made by the
certificate is only respected if it is over a user ID with an email address in the specified
domain. Multiple domains may be specified. In that case, one must match.

--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.

[default: never]

--recreate
Recreate the signature even if the parameters did not change

If the link parameters did not change, and thus creating a signature should not be necessary, we
omit the operation. This flag can be given to force the signature to be recreated anyway.

--regex=REGEX
Add a regular expression to constrain the introducer

Add a regular expression to constrain what certifications are respected. A certification made by
the certificate is only respected if it is over a user ID that matches one of the specified
regular expression. Multiple regular expressions may be specified. In that case, at least one
must match.

--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.

--unconstrained
Don't constrain the introducer

Normally an introducer is constrained so that only certain user IDs are respected, e.g., those
that have an email address for a certain domain name. This option authorizes an introducer
without constraining it in this way. Because this grants the introducer a lot of power, you have
to opt in to this behavior explicitly.

--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.

EXAMPLES

       Add an unconstrained trusted introducer.

              sq pki link authorize --unconstrained \
                     --cert=EB28F26E2739A4870ECC47726F0073F60FD0CBF0 --all

       Add a trusted introducer for example.org and example.com.

              sq pki link authorize --domain=example.org \
                     --domain=example.com \
                     --cert=EB28F26E2739A4870ECC47726F0073F60FD0CBF0 --all

       Add a partially trusted introducer.

              sq pki link authorize --unconstrained --amount=60 \
                     --cert=EB28F26E2739A4870ECC47726F0073F60FD0CBF0 --all
