NAME

6       GnuPG::Signature - GnuPG Key Signature Objects
7

SYNOPSIS

9         # assumes a GnuPG::Key or GnuPG::UserID or GnuPG::UserAttribute object in $signed
10         my $signing_id = $signed->signatures->[0]->hex_id();
11

DESCRIPTION

13       GnuPG::Signature objects are generally not instantiated on their own,
14       but rather as part of GnuPG::Key objects.  They embody various aspects
15       of a GnuPG signature on a key.
16

OBJECT METHODS

18       new( %initialization_args )
19           This methods creates a new object.  The optional arguments are
20           initialization of data members.
21
22       is_valid()
23           Returns 1 if GnuPG was able to cryptographically verify the
24           signature, otherwise 0.
25
26       compare( $other )
27           Returns non-zero only when this Signature is identical to the other
28           GnuPG::Signature.
29

OBJECT DATA MEMBERS

31       validity
32           A character indicating the cryptographic validity of the key.
33           GnuPG uses at least the following characters: "!" means valid, "-"
34           means not valid, "?" means unknown (e.g. if the supposed signing
35           key is not present in the local keyring), and "%" means an error
36           occurred (e.g. a non-supported algorithm).  See the documentation
37           for --check-sigs in gpg(1).
38
39       algo_num
40           The number of the algorithm used for the signature.
41
42       hex_id
43           The hex id of the signing key.
44
45       user_id_string
46           The first user id string on the key that made the signature.  This
47           may not be defined if the signing key is not on the local keyring.
48
49       sig_class
50           Signature class.  This is the numeric value of the class of
51           signature.
52
53           A table of possible classes of signatures and their numeric types
54           can be found at http://tools.ietf.org/html/rfc4880#section-5.2.1
55
56       is_exportable
57           returns 0 for local-only signatures, non-zero for exportable
58           signatures.
59
60       date_string
61           The formatted date the signature was performed on.
62
63       date
64           The date the signature was performed, represented as the number of
65           seconds since midnight 1970-01-01 UTC.
66
67       expiration_date_string
68           The formatted date the signature will expire (signatures without
69           expiration return undef).
70
71       expiration_date
72           The date the signature will expire, represented as the number of
73           seconds since midnight 1970-01-01 UTC (signatures without
74           expiration return undef)
