NAME

6       Mail::DKIM::ARC::Signature - represents a ARC-Message-Signature header
7
8       This is a subclass of Mail::DKIM::Signature
9

CONSTRUCTORS

11   new() - create a new signature from parameters
12         my $signature = Mail::DKIM::ARC::MessageSignature->new(
13                             [ Algorithm => 'rsa-sha256', ]
14                             [ Signature => $base64, ]
15                             [ Method => 'relaxed', ]
16                             [ Domain => 'example.org', ]
17                             [ Instance => 1, ]
18                             [ Headers => 'from:subject:date:message-id', ]
19                             [ Query => 'dns', ]
20                             [ Selector => 'alpha', ]
21                             [ Timestamp => time(), ]
22                             [ Expiration => time() + 86400, ]
23                         );
24
25       The only differences between this module and Mail::DKIM::Signature are
26       the header name, and that 'instance' is an integer rather than a base64
27       encoded value.
28
29   instance() - get or set the signing instance (i=) field
30         my $i = $signature->instance;
31
32       Instances must be integers less than 1024 according to the spec.
33
34       NOTE: the i= field is "Identity" in DKIM and is a base64 value, but in
35       ARC it is "Instance" and an integer.  The parsing routine does not
36       check that the i= value is a number.
