SQ(1)

NAME
sq key adopt - Binds keys from one certificate to another

SYNOPSIS
sq key adopt [OPTIONS] TARGET-KEY

DESCRIPTION
Binds keys from one certificate to another.

This command allows one to transfer primary keys and subkeys into an existing certificate. Say you want to transition to a new certificate, but have an authentication subkey on your current certificate. You want to keep the authentication subkey because it allows access to SSH servers and updating their configuration is not feasible.

OPTIONS

  Subcommand options

-B, --binary
    Emits binary data

--allow-broken-crypto
    Allows adopting keys from certificates using broken cryptography

--expire=KEY-EXPIRATION-TIME
    Makes adopted subkeys expire at the given time

-k, --key=KEY
    Adds the key or subkey KEY to the TARGET-KEY

-o, --output=FILE
    Writes to FILE or stdout if omitted

TARGET-KEY
    Adds keys to TARGET-KEY or reads keys 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

Adopt an subkey into the new cert

    sq key adopt --keyring juliet-old.pgp --key 0123456789ABCDEF \
        juliet-new.pgp
