NAME

6       Mail::DKIM::ARC::MessageSignature - Subclass of Mail::DKIM::Signature
7       which represents a ARC-Message-Signature header
8

VERSION

10       version 1.20200907
11

CONSTRUCTORS

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