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)
