# GnuPG::SubKey(3pm)

GnuPG Sub Key objects

## NAME

GnuPG::SubKey - GnuPG Sub Key objects

## SYNOPSIS

```
  # assumes a GnuPG::PublicKey object in $key
  my @subkeys = $key->subkeys();
  # now GnuPG::SubKey objects are in @subkeys
```

## DESCRIPTION

GnuPG::SubKey objects are generally instantiated through various methods of GnuPG::Interface. They embody various aspects of a GnuPG sub key.

This package inherits data members and object methods from GnuPG::Key, which are not described here, but rather in GnuPG::Key.

## OBJECT DATA MEMBERS

- validity

  A scalar holding the value GnuPG reports for the trust of authenticity (a.k.a.) validity of a key. See GnuPG's DETAILS file for details.

- local\_id

  GnuPG's local id for the key.

- owner\_trust

  The scalar value GnuPG reports as the ownertrust for this key. See GnuPG's DETAILS file for details.

- signature

  \* DEPRECATED\*

  A GnuPG::Signature object holding the representation of the signature on this key.  Please use signatures (see GnuPG::Key) instead of signature.  Using signature, you will get an arbitrary signature from the set of available signatures.
