NAME
       GnuPG::Signature - GnuPG Key Signature Objects

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

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

OBJECT METHODS
       new( %initialization_args )
           This methods creates a new object.  The optional arguments are
           initialization of data members.

       is_valid()
           Returns 1 if GnuPG was able to cryptographically verify the
           signature, otherwise 0.

       compare( $other )
           Returns non-zero only when this Signature is identical to the other
           GnuPG::Signature.

OBJECT DATA MEMBERS
       validity
           A character indicating the cryptographic validity of the key.
           GnuPG uses at least the following characters: "!" means valid, "-"
           means not valid, "?" means unknown (e.g. if the supposed signing
           key is not present in the local keyring), and "%" means an error
           occurred (e.g. a non-supported algorithm).  See the documentation
           for --check-sigs in gpg(1).

       algo_num
           The number of the algorithm used for the signature.

       hex_id
           The hex id of the signing key.

       user_id_string
           The first user id string on the key that made the signature.  This
           may not be defined if the signing key is not on the local keyring.

       sig_class
           Signature class.  This is the numeric value of the class of
           signature.

           A table of possible classes of signatures and their numeric types
           can be found at http://tools.ietf.org/html/rfc4880#section-5.2.1

       is_exportable
           returns 0 for local-only signatures, non-zero for exportable
           signatures.

       date_string
           The formatted date the signature was performed on.

       date
           The date the signature was performed, represented as the number of
           seconds since midnight 1970-01-01 UTC.

       expiration_date_string
           The formatted date the signature will expire (signatures without
           expiration return undef).

       expiration_date
           The date the signature will expire, represented as the number of
           seconds since midnight 1970-01-01 UTC (signatures without
           expiration return undef)
