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)

NAME

       GnuPG::Revoker - GnuPG Key Revoker Objects

SYNOPSIS

	 # assumes a GnuPG::PrimaryKey object in $key
	 my $revokerfpr = $key->revokers->[0]->fingerprint();

DESCRIPTION

       GnuPG::Revoker objects are generally not instantiated on their own, but rather as part of GnuPG::Key objects.  They represent a statement
       that another key is designated to revoke certifications made by the key in question.

OBJECT METHODS

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

       is_sensitive()
	   Returns 0 if the revoker information can be freely distributed.  If this is non-zero, the information should be treated as "sensitive".

	   Please see http://tools.ietf.org/html/rfc4880#section-5.2.3.15 for more explanation.

       compare( $other, $deep )
	   Returns non-zero only when this designated revoker is identical to the other GnuPG::Revoker.  If $deep is present and non-zero, the
	   revokers' signatures will also be compared.

OBJECT DATA MEMBERS

       fingerprint
	   A GnuPG::Fingerprint object indicating the fingerprint of the specified revoking key.  (Note that this is *not* the fingerprint of the
	   key whose signatures can be revoked by this revoker).

       algo_num
	   The numeric identifier of the algorithm of the revoker's key.

       signatures
	   A list of GnuPG::Signature objects which cryptographically bind the designated revoker to the primary key.  If the material was
	   instantiated using the *_with_sigs() functions from GnuPG::Interface, then a valid revoker designation should have a valid signature
	   associated with it from the relevant key doing the designation (not from the revoker's key).

	   Note that designated revoker certifications are themselves irrevocable, so there is no analogous list of revocations in a
	   GnuPG::Revoker object.
