SQ(1)

NAME
sq-network - Retrieve and publish certificates over the network

SYNOPSIS
sq network search [OPTIONS] QUERY
sq network keyserver [OPTIONS] SUBCOMMAND
sq network wkd [OPTIONS] SUBCOMMAND
sq network dane [OPTIONS] SUBCOMMAND

DESCRIPTION
Retrieve and publish certificates over the network.

OpenPGP certificates can be discovered and updated from, and published on services accessible over the network. This is a collection of commands to interact with these services.

SUBCOMMANDS

  sq network search
Retrieve certificates using all supported network services.

This command will try to locate relevant certificates given a query, which may be a fingerprint, a key ID, an email address, or a https URL. It may also discover and import certificate related to the one queried, such as alternative certs, expired certs, or revoked certs.

Discovering related certs is useful: alternative certs support key rotations, expired certs allow verification of signatures made in the past, and discovering revoked certs is important to get the revocation information. The PKI mechanism will help to select the correct cert, see `sq pki`.

By default, any returned certificates are stored in the local certificate store. This can be overridden by using `--output` option.

When a certificate is retrieved from a verifying key server (currently, this is limited to a list of known servers: `hkps://keys.openpgp.org`, `hkps://keys.mailvelope.com`, and `hkps://mail-api.proton.me`), WKD, DANE, or via https, and imported into the local certificate store, the User IDs are also certificated with a local server-specific key. That proxy certificate is in turn certified as a minimally trusted CA (trust amount: 1 of 120) by the local trust root. How much a proxy key server CA is trusted can be tuned using `sq pki link add` or `sq pki link retract` in the usual way.

  sq network keyserver
Retrieve and publishes certificates via key servers.

The OpenPGP HTTP Keyserver Protocol (HKP) is a method for publishing and retrieving certificates from key servers.

  sq network wkd
Retrieve and publishes certificates via Web Key Directories.

The Web Key Directory (WKD) is a method for publishing and retrieving certificates from web servers.

  sq network dane
Retrieve and publishes certificates via DANE.

DNS-Based Authentication of Named Entities (DANE) is a method for publishing and retrieving certificates in DNS as specified in RFC 7929.
