Manages keys.

We use the term "key" to refer to OpenPGP keys that do contain secrets. This subcommand provides primitives to generate and otherwise manipulate keys.

Conversely, we use the term "certificate", or "cert" for short, to refer to OpenPGP keys that do not contain secrets. See `sq toolbox keyring` for operations on certificates.

sq key list

Lists keys managed by the key store.

sq key generate

Generates 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 a revocation certificate. This can be used in case the key is superseded, lost, or compromised. It is a good idea to keep a copy of this in a safe place.

After generating a key, use `sq key extract-cert` to get the certificate corresponding to the key. The key must be kept secure, while the certificate should be handed out to correspondents, e.g. by uploading it to a key server.

By default a key expires after 3 years. Using the `--expiry=` argument specific validity periods may be defined. It allows for providing a point in time for validity to end or a validity duration.

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

sq key import

Import keys into the key store.

sq key password

Changes password protecting secrets.

Secret key material in keys can be protected by a password. This subcommand changes or clears this encryption password.

To emit the key with unencrypted secrets, either use `--clear` or supply a zero-length password when prompted for the new password.

sq key expire

Changes expiration times.

Keys and their individual subkeys can expire. This subcommand changes or clears the expiration times.

By default, the expiration time of the entire key is changed. To change the expiration of only some of the subkeys, use the `--subkey` option.

Revokes a certificate.

Creates a revocation certificate for the certificate.

If `--revocation-file` is provided, then that key is used to create the signature. If that key is different from the certificate being revoked, this creates a third-party revocation. This is normally only useful if the owner of the certificate designated the key to be a designated revoker.

If `--revocation-file` is not provided, then the certificate must include a certification-capable key.

`sq key revoke` respects the reference time set by the top-level `--time` argument. When set, it uses the specified time instead of the current time, when determining what keys are valid, and it sets the revocation certificate's creation time to the reference time instead of the current time.

Manages User IDs.

Add User IDs to, or strip User IDs from a key.

Manages Subkeys.

Add new subkeys to an existing key.

sq key extract-cert

Converts a key to a cert.

After generating a key, use this command to get the certificate corresponding to the key. The key must be kept secure, while the certificate should be handed out to correspondents, e.g. by uploading it to a key server.

sq key attest-certifications

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.

sq key adopt

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.

sq key list

Lists the keys managed by the keystore server.

sq key list

sq key generate

First, generate a key

sq key generate --userid '<juliet@example.org>' \
--output juliet.key.pgp

Then, extract the certificate for distribution

sq key extract-cert --output juliet.cert.pgp juliet.key.pgp

Generate a key protecting it with a password

sq key generate --userid '<juliet@example.org>' --with-password

Generate a key with multiple userids

sq key generate --userid '<juliet@example.org>' \
--userid 'Juliet Capulet'

Generate a key whose creation time is June 9, 2011 at midnight UTC

sq key generate --time 20110609 --userid Noam \
--output noam.pgp

sq key import

Import the keys into the keystore server.

sq key import alice-secret.pgp

sq key password

First, generate a key

sq key generate --userid '<juliet@example.org>' \
--output juliet.key.pgp

Then, encrypt the secrets in the key with a password.

sq key password < juliet.key.pgp > juliet.encrypted_key.pgp

And remove the password again.

sq key password --clear < juliet.encrypted_key.pgp \
> juliet.decrypted_key.pgp

sq key expire

Make Alice's key expire in a year.

sq key expire 1y alice-secret.pgp

Make Alice's key never expire.

sq key expire never alice-secret.pgp

Make Bob's authentication subkey expire in six months.

sq key expire 6m --subkey 6AEACDD24F896624 bob-secret.pgp

sq key extract-cert

First, generate a key

sq key generate --userid '<juliet@example.org>' \
--output juliet.key.pgp

Then, extract the certificate for distribution

sq key extract-cert --output juliet.cert.pgp juliet.key.pgp

sq key attest-certifications

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

sq key adopt

Adopt an subkey into the new cert

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