Subcommand options

--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-userid=USERID

Create the certification using the key with the specified user ID

--email=EMAIL

Use the self-signed user ID with the specified email address

--email-or-add=EMAIL

Use a user ID with the specified email address.

This first searches for a matching self-signed user ID. If there is no self-signed user ID with the specified email address, it uses a new user ID with the specified email address, and no display name.

--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: 5y]

--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 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 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-or-add=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. That said, certifying a user ID that is not self-signed is useful. For instance, you can associate an alternate email address with a certificate, or you can add a petname, i.e., a memorable, personal name like "mom".
