Attests to third-party certifications

Synopsis

sq key attest-certifications [Options] KEY

Description

Attests to third-party certifications allowing for their distribution.

To prevent certificate flooding attacks, modern key servers prevent uncontrolled distribution of third-party certifications on certificates.  To make the key holder the sovereign over the information over what information is distributed with the certificate, the key holder needs to explicitly attest to third-party certifications.

After the attestation has been created, the certificate has to be distributed, e.g. by uploading it to a key server.

Options

Subcommand options

-B, --binary

Emits binary data

--all

Attests to all certifications [default]

--none

Removes all prior attestations

-o, --output=FILE

Writes to FILE or stdout if omitted

KEY

Changes attestations on KEY or reads from stdin if omitted

Global options

--cert-store=PATH

Specifies the location of the certificate store.  By default, sq uses the OpenPGP certificate directory at `$HOME/.local/share/pgp.cert.d`, and creates it if it does not exist.

-f,  --force

Overwrites existing files

-h,  --help

Print help (see a summary with '-h')

--keyring=PATH

Specifies the location of a keyring to use.  Keyrings are used in addition to any certificate store.  The content of the keyring is not imported into the certificate store.  When a certificate is looked up, it is looked up in all keyrings and any certificate store, and the results are merged together.

--known-notation=NOTATION

Adds NOTATION to the list of known notations. This is used when validating signatures. Signatures that have unknown notations with the critical bit set are considered invalid.

--no-cert-store

Disables the use of a certificate store.  Normally sq uses the user's standard cert-d, which is located in `$HOME/.local/share/pgp.cert.d`.

--output-format=FORMAT

Produces output in FORMAT, if possible

--output-version=VERSION

Produces output variant Version, such as 0.0.0. The default is the newest version. The output version is separate from the version of the sq program. To see the current supported versions, use output-versions subcommand.

--pep-cert-store=PATH

Specifies the location of a pEp certificate store.  sq does not use a pEp certificate store by default; it must be explicitly enabled using this argument or the corresponding environment variable, PEP_CERT_STORE.  The pEp Engine's default certificate store is at `$HOME/.pEp/keys.db`.

--time=TIME

Sets the reference time as an ISO 8601 formatted timestamp.  Normally, commands use the current time as the reference time.  This argument allows the user to use a difference reference time.  For instance, when creating a key using `sq key generate`, the creation time is normally set to the current time, but can be overridden using this option.  Similarly, when verifying a message, the message is verified with respect to the current time.  This option allows the user to use a different time.

TIME is interpreted as an ISO 8601 timestamp.  To set the certification time to July 21, 2013 at midnight UTC, you can do:

$ sq --time 20130721 verify msg.pgp

To include a time, say 5:50 AM, add a T, the time and optionally the timezone (the default timezone is UTC):

$ sq --time 20130721T0550+0200 verify msg.pgp

--trust-root=FINGERPRINT|KEYID

Considers the specified certificate to be a trust root. Trust roots are used by trust models, e.g., the Web of Trust, to authenticate certificates and User IDs.

-v,  --verbose

Be more verbose.

Examples

Attest to all certifications present on the key

    sq key attest-certifications juliet.pgp

Retract prior attestations on the key

    sq key attest-certifications --none juliet.pgp
