NAME

       sequoia-keyring-linter - A linter for keyrings

SYNOPSIS

       sequoia-keyring-linter  [-t|--time]  [-q|--quiet]  [-f|--fix]  [-e|--export-secret-keys]  [-p|--password]
       [-k|--list-keys] [-h|--help] [-V|--version] [FILE]

DESCRIPTION

       A linter for keyrings

OPTIONS

-t, --time=TIME
Sets the reference time to TIME.

TIME is interpreted as an ISO 8601 timestamp. To set the reference time to July 21, 2013 at
midnight UTC, you can do:

$ sq-keyring-linter --time 20130721 ...

To include a time, add a T, the time and optionally the timezone (the default timezone is UTC):

$ sq-keyring-linter --time 20130721T0550+0200 ...

-q, --quiet=QUIET
Quiet; does not output any diagnostics

-f, --fix=FIX
Attempts to fix certificates, when possible

-e, --export-secret-keys=EXPORT_SECRET_KEYS
When fixing a certificate, the fixed certificate is exported without any secret key material.
Using this switch causes any secret key material to also be exported.

-p, --password=PASSWORD
A key's password. Normally this is not needed: if stdin is connected to a tty, the linter will ask
for a password when needed.

-k, --list-keys=LIST_KEYS
If set, outputs a list of fingerprints, one per line, of certificates that have issues. This
output is intended for use by scripts.

This option implies "--quiet". If you also specify "--fix", errors will still be printed to
stderr, and fixed certificates will still be emitted to stdout.

-h, --help
Print help information (use `-h` for a summary)

-V, --version
Print version information

[FILE] A list of OpenPGP keyrings to process. If none are specified, a keyring is read from stdin.

EXTRA

`sq-keyring-linter` 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.

EXIT STATUS:

If `--fix` is not specified:
2 if any issues were found,
1 if not issues were found, but there were errors reading the input,
0 if there were no issues.

If `--fix` is specified:
3 if any issues could not be fixed,
1 if not issues were found, but there were errors reading the input,
0 if all issues were fixed or there were no issues.

EXAMPLES:

# To gather statistics, simply run:
$ sq-keyring-linter keyring.pgp

# To fix a key:
$ gpg --export-secret-keys FPR | sq-keyring-linter --fix -p passw0rd -p password123 | gpg --import

# To get a list of keys with issues:
$ sq-keyring-linter --list-keys keyring.pgp | while read FPR; do something; done
