SQ(1) User Commands SQ(1) NAME sq pki link add - Link a certificate and a User ID SYNOPSIS sq pki link add [OPTIONS] FINGERPRINT|KEYID USERID|EMAIL DESCRIPTION Link a certificate and a User ID. This cause `sq` to considers the certificate and User ID binding to be authentic. A certificate can also be accepted as a certification authority, which is also known as a trusted introducer, by using the `--ca` or `--depth` option. A link can be retracted using `sq pki link retract`. This command is similar to `sq pki certify`, but the certifications it makes are done using the certificate directory's trust root, not an ar- bitrary key. Further, the certificates are marked as non-exportable. The former makes it easier to manage certifications, especially when the user's certification key is offline. And the latter improves the user's privacy, by reducing the chance that parts of the user's social graph is leaked when a certificate is shared. By default a link never expires. Using the `--expiry` argument spe- cific validity periods may be defined. It allows for providing a point in time for validity to end or a validity duration. `sq pki link` 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 -a, --amount=AMOUNT Set the amount of trust. Values between 1 and 120 are meaning- ful. 120 means fully trusted. Values less than 120 indicate the degree of trust. 60 is usually used for partially trusted. [default: full] --all Link all valid self-signed User ID to the certificate. --ca=*|DOMAIN Mark the certificate as a certification authority for a domain. Use `*` to make the certificate a certification authority for any User ID. A certification authority is also referred to as a trusted introducer. This command is equivalent to making the trust depth unconstrained, i.e., setting the depth to 255. See `--depth` for more information. -d, --depth=TRUST_DEPTH Set the trust depth (sometimes referred to as the trust level). 0 means a normal certification of <CERTIFICATE, USERID>. 1 means CERTIFICATE is also a trusted introducer, 2 means CERTIFI- CATE is a meta-trusted introducer, etc. --email=EMAIL An email address to link to the certificate. The email address must match the email address of a self-signed User ID. To link an email address to the certificate that does not appear in a self-signed User ID, use `--petname`. If the specified email appears in multiple self-signed User IDs, then all of them are linked. --expiry=EXPIRY Define EXPIRY for the acceptance as ISO 8601 formatted string or custom duration. If an ISO 8601 formatted string is provided, the validity period reaches from the reference time (may be set using `--time`) to the provided time. Custom durations starting from the reference time may be set using `N[ymwds]`, for N years, months, weeks, days, or seconds. The special keyword `never` sets an unlimited expiry. [default: never] --notation NAME VALUE Add a notation to the certification. 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 under- stand a critical notation, then it will ignore the signature. The notation is marked as being human readable. --petname=PETNAME A User ID to link to the certificate. Unlike `--userid`, this does not need to match a self-signed User ID. Bare email ad- dress are automatically wrapped in angle brackets. That is if `alice@example.org` is provided, it is silently converted to `<alice@example.org>`. -r, --regex=REGEX Add a regular expression to constrain what a trusted introducer can certify. The regular expression must match the certified User ID in all intermediate introducers, and the certified cer- tificate. Multiple regular expressions may be specified. In that case, at least one must match. --temporary Temporarily accepts the binding. Creates a fully trust link between a certificate and one or more User IDs for a week. After that, the link is automatically downgraded to a partially trusted link (trust = 40). --userid=USERID A User ID to link to the certificate. This must match a self-signed User ID. To link a User ID to the certificate that does not have a self-signature, use `--petname`. FINGERPRINT|KEYID The certificate to accept. USERID|EMAIL A User ID or email address to link to the certificate. This must match a self-signed User ID. To link a User ID to the cer- tificate that does not have a self-signature, use `--petname`. Scripts should prefer to use `--email` or `--userid`, as `sq` does not need to guess if a value is a User ID or an email ad- dress. Global options See sq(1) for a description of the global options. EXAMPLES The user links 0123456789ABCDEF and the User ID '<romeo@example.org>'. sq pki link add 0123456789ABCDEF '<romeo@example.org>' The user examines 0123456789ABCDEF and then accepts the certificate 0123456789ABCDEF with its current set of self-signed User IDs. sq cert export --cert 0123456789ABCDEF | sq inspect ... sq pki link add 0123456789ABCDEF --all The user links the certificate and its current self-signed User IDs for a week. sq pki link add --expires-in 1w 0123456789ABCDEF --all The user accepts the certificate, and its current self-signed User IDs as a certification authority. That is, the certificate is considered a trust root. sq pki link add --ca '*' 0123456789ABCDEF --all The user accepts the certificate and its current self-signed User IDs as a partially trusted certification authority. sq pki link add --ca '*' --amount 60 0123456789ABCDEF --all The user retracts their acceptance of 0123456789ABCDEF and any associ- ated User IDs. This effectively invalidates any links. sq pki link retract 0123456789ABCDEF SEE ALSO sq(1), sq-pki(1), sq-pki-link(1). For the full documentation see <https://book.sequoia-pgp.org>.
