NAME

sq-cert-lint - Check certificates for issues

SYNOPSIS

sq cert lint [OPTIONS]

DESCRIPTION

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.

OPTIONS

Subcommand options

Use certificates with the specified fingerprint or key ID
Use certificates where a user ID includes an email address for the specified domain
Use certificates where a user ID includes the specified email address
Read certificates from PATH
Use certificates with a user ID that matches the pattern, case insensitively
Use certificates with the specified user ID
Attempts to fix certificates, when possible
Write to the specified FILE
If not specified, and the certificate was read from the certificate store, imports the modified certificate into the cert store. If not specified, and the certificate was read from a file, writes the modified certificate to stdout.

Global options

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