Mail::DKIM::ARC::MessaUsergContributed PMail::DKIM::ARC::MessageSignature(3pm)
NAME
Mail::DKIM::ARC::MessageSignature - Subclass of Mail::DKIM::Signature
which represents a ARC-Message-Signature header
VERSION
version 1.20200907
CONSTRUCTORS
new() - create a new signature from parameters
my $signature = Mail::DKIM::ARC::MessageSignature->new(
[ Algorithm => 'rsa-sha256', ]
[ Signature => $base64, ]
[ Method => 'relaxed', ]
[ Domain => 'example.org', ]
[ Instance => 1, ]
[ Headers => 'from:subject:date:message-id', ]
[ Query => 'dns', ]
[ Selector => 'alpha', ]
[ Timestamp => time(), ]
[ Expiration => time() + 86400, ]
);
The only differences between this module and Mail::DKIM::Signature are
the header name, and that 'instance' is an integer rather than a base64
encoded value.
instance() - get or set the signing instance (i=) field
my $i = $signature->instance;
Instances must be integers less than 1024 according to the spec.
NOTE: the i= field is "Identity" in DKIM and is a base64 value, but in
ARC it is "Instance" and an integer. The parsing routine does not
check that the i= value is a number.
