NAME

       Mail::Message::Field::DKIM - message header field for dkim signatures

INHERITANCE

        Mail::Message::Field::DKIM
          is a Mail::Message::Field::Structured
          is a Mail::Message::Field::Full
          is a Mail::Message::Field
          is a Mail::Reporter

SYNOPSIS

        my $f = Mail::Message::Field->new('DKIM-Signature' => '...');

        my $g = Mail::Message::Field->new('DKIM-Signature');
        $g->add...

DESCRIPTION

       Decode the information contained in a DKIM header.  You can also construct DKIM-Signature
       headers this way.  However, verification and signing is not yet implemented.

       This implementation is based on RFC6376.

       The tag methods return the tag-value content without any validation or modification.  For
       many situations, the actual content does not need (expensive) validation and
       interpretation.

           body was used.

       $obj->tagC14N()
           The canonicalization method used.  Defaults to 'simple/simple'.

       $obj->tagDomain()
           The sub-domain (SDID) which claims responsibility for this signature. Required.

       $obj->tagExpires()
           The timestamp when the signature will expire.  Recommended.

       $obj->tagExtract()
           Some headers from the original message packed together.

       $obj->tagQueryMethods()
           A colon-separated list of method which can be used to retrieve the public key.  The
           default is "dns/txt" (currently the only valid option)

       $obj->tagSelector()
           The selector subdividing the $domain tag.  Required.

       $obj->tagSignData()
       $obj->tagSignature()
           Message signature in base64, with whitespaces removed. Required.

       $obj->tagSignedHeaders()
           The colon separated list of headers which need to be included in the signature.
           Required.

       $obj->tagTimestamp()
           When the signature was created in UNIX-like seconds (since 1970).  Recommended.

DIAGNOSTICS

       Warning: Field content is not numerical: $content
           The numeric value of a field is requested (for instance the "Lines" or
           "Content-Length" fields should be numerical), however the data contains weird
           characters.

       Warning: Illegal character in charset '$charset'
           The field is created with an utf8 string which only contains data from the specified
           character set.  However, that character set can never be a valid name because it
           contains characters which are not permitted.

       Warning: Illegal character in field name $name
           A new field is being created which does contain characters not permitted by the RFCs.
           Using this field in messages may break other e-mail clients or transfer agents, and
           therefore mutulate or extinguish your message.

       Warning: Illegal character in language '$lang'
           The field is created with data which is specified to be in a certain language,
           however, the name of the language cannot be valid: it contains characters which are
           not permitted by the RFCs.

       Warning: Illegal encoding '$encoding', used 'q'
           The RFCs only permit base64 ("b " or "B ") or quoted-printable ("q" or "Q") encoding.
           Other than these four options are illegal.

       Error: No attributes for DKIM headers
           Is is not possible to add attributes to this field.

       Error: Package $package does not implement $method.
           Fatal error: the specific package (or one of its superclasses) does not implement this
           method where it should. This message means that some other related classes do
           implement this method however the class at hand does not.  Probably you should
           investigate this and probably inform the author of the package.
