Generate a new key

Synopsis

sq key generate [Options]  

Description

Generate a new key.

Generating a key is the prerequisite to receiving encrypted messages and creating signatures.  There are a few parameters to this process, but we provide reasonable defaults for most users.

When generating a key, we also generate an emergency revocation certificate. This can be used in case the key is lost or compromised.  It is saved alongside the key.  This can be changed using the `--rev-cert` argument.

By default a key expires after 3 years.  This can be changed using the `--expiration` argument.

`sq key generate` respects the reference time set by the top-level `--time` argument.  It sets the creation time of the primary key, any subkeys, and the binding signatures to the reference time.

Options

Subcommand options

--allow-non-canonical-userids

Don't reject user IDs that are not in canonical form.

Canonical user IDs are of the form `Name (Comment) <localpart@example.org>`.

--can-authenticate

Add an authentication-capable subkey (default)

--can-encrypt=PURPOSE

Add an encryption-capable subkey.

Encryption-capable subkeys can be marked as suitable for transport encryption, storage encryption, or both, i.e., universal.  [default: universal]

[possible values: transport, storage, universal]

--can-sign

Add a signing-capable subkey (default)

--cannot-authenticate

Don't add an authentication-capable subkey

--cannot-encrypt

Don't add an encryption-capable subkey

--cannot-sign

Don't add a signing-capable subkey

--cipher-suite=CIPHER-SUITE

Select the cryptographic algorithms for the key

[default: cv25519]

[possible values: rsa2k, rsa3k, rsa4k, cv25519]

--email=ADDRESS

Add an email address as user ID to the key

--expiration=EXPIRATION

Sets the certificate's expiration time.

EXPIRATION is either an ISO 8601 formatted string or a custom duration, which 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.

When using an ISO 8601 formatted string, the validity period is from the certificate's creation time to the specified time.  When using a duration, the validity period is from the certificate's creation time for the specified duration.

[default: 3y]

--name=NAME

Add a name as user ID to the key

--new-password-file=PASSWORD_FILE

File containing password to encrypt the secret key material.

Note that the entire key file will be used as the password including any surrounding whitespace like a trailing newline.

--no-userids

Create a key without any user IDs

--output=FILE

Write the key to the specified file.

When not specified, the key is saved on the key store.

--rev-cert=FILE

Write the emergency revocation certificate to FILE.

When the key is stored on the key store, the revocation certificate is stored in $HOME/.local/share/sequoia/revocation-certificates by default.

When `--output` is specified, the revocation certificate is written to `FILE.rev` by default.

If `--output` is `-`, then this option must be provided.

--userid=USERID

Add a user ID to the key.

This user ID can combine name and email address, can optionally contain a comment, or even be free-form if `--allow-non-canonical-userids` is given.  However, user IDs that include different information such as name and email address are more difficult to reason about, so using distinct user IDs for name and email address is preferred nowadays.

In doubt, prefer `--name` and `--email`.

--without-password

Don't protect the secret key material with a password

Global options

See sq(1) for a description of the global options.

Examples

Generate a key, and save it on the key store.

    sq key generate --without-password --name Alice --email \
    alice@example.org

Generate a key, and save it in a file instead of in the key store.

    sq key generate --without-password --name Alice --email \
    alice@example.org --output alice-priv.pgp

Strip the secret key material from the new key.

    sq toolbox extract-cert alice-priv.pgp --output alice.pgp
