Ubuntu Manpage: sq cert - Manage certificates

NAME

       sq cert - Manage certificates

SYNOPSIS

       sq cert import [OPTIONS] FILE
       sq cert export [OPTIONS] QUERY
       sq cert lint [OPTIONS] FILE

DESCRIPTION

       Manage certificates.

       We  use  the term "certificate", or "cert" for short, to refer to OpenPGP keys that do not
       contain secrets.  This subcommand provides primitives to generate and otherwise manipulate
       certs.

       Conversely,  we  use the term "key" to refer to OpenPGP keys that do contain secrets.  See
       `sq key` for operations on keys.

SUBCOMMANDS

sq cert import
Import certificates into the local certificate store.

sq cert export
Export certificates from the local certificate store.

If multiple predicates are specified a certificate is returned if at least one of them
matches.

This does not check the authenticity of the certificates in anyway. Before using the
certificates, be sure to validate and authenticate them.

When matching on subkeys or User IDs, the component must have a valid self signature
according to the policy. This is not the case when matching the certificate's key handle
using `--cert` or when exporting all certificates.

Fails if search criteria are specified and none of them matches any certificates. Note:
this means if the certificate store is empty and no search criteria are specified, then
this will return success.

sq cert lint
Check certificates for issues.

`sq cert lint` checks the supplied certificates for the following SHA-1-related issues:

- Whether a certificate revocation uses SHA-1.

- Whether the current self signature for a non-revoked User ID uses
SHA-1.

- Whether the current subkey binding signature for a non-revoked,
live subkey uses SHA-1.

- Whether a primary key binding signature ("backsig") for a
non-revoked, live subkey uses SHA-1.

Diagnostics are printed to stderr. At the end, some statistics are shown. This is useful
when examining a keyring. If `--fix` is specified and at least one issue could be fixed,
the fixed certificates are printed to stdout.

This tool does not currently support smart cards. But, if only the subkeys are on a smart
card, this tool may still be able to partially repair the certificate. In particular, it
will be able to fix any issues with User ID self signatures and subkey binding signatures
for encryption-capable subkeys, but it will not be able to generate new primary key
binding signatures for any signing-capable subkeys.

EXAMPLES

sq cert import
Import a certificate.

sq cert import juliet.pgp

sq cert export
Export all certificates.

sq cert export --all

Export certificates with a matching User ID packet. The binding signatures are checked,
but the User IDs are not authenticated. Note: this check is case sensitive.

sq cert export --userid "Alice <alice@example.org>"

Export certificates with a User ID containing the email address. The binding signatures
are checked, but the User IDs are not authenticated. Note: this check is case
insensitive.

sq cert export --email alice@example.org

Export certificates where the certificate (i.e., the primary key) has the specified Key
ID.

sq cert export --cert 6F0073F60FD0CBF0

Export certificates where the primary key or a subkey matches the specified Key ID.

sq cert export --key 24F3955B0B8DECC8

Export certificates that contain a User ID with *either* (not both!) email address.
Note: this check is case insensitive.

sq cert export --email alice@example.org --email \
bob@example.org

sq cert lint
To gather statistics, simply run:

sq cert lint keyring.pgp

To fix a key:

gpg --export-secret-keys FPR \
| sq cert lint --fix -p passw0rd -p password123 \
| gpg --import

To get a list of keys with issues:

sq cert lint --list-keys keyring.pgp \
| while read FPR; do something; done
