Description

sq-keyring-linter 0.5.0

"sq-keyring-linter" checks for and optionally repairs OpenPGP certificates that use SHA-1.

Usage

sq-keyring-linter [Flags] [Options] [--] [FILES]...

Flags

-e,  --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.

-f,  --fix

Attempts to fix certificates, when possible

-h,  --help

Prints help information

-k,  --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.

-q,  --quiet

Quiet; does not output any diagnostics

-V,  --version

Prints version information

Options

-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.

Args

<FILES>...

A list of OpenPGP keyrings to process.

If none are

specified, a keyring is read from stdin.

"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 (a "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
