GnuPG::Signature(3) User Contributed Perl Documentation GnuPG::Signature(3)NAMEGnuPG::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();
DESCRIPTIONGnuPG::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)
