NAME

MIME::Signature - appends signature to mail messages

VERSION

Version 0.16

SYNOPSIS

    my $ms = MIME::Signature->new(
        plain => 'Das ist der Rand von Ostermundigen.' 
    );
    $ms->parse( \*STDIN );
    $ms->append;
    $ms->entity->print;

Or, alternatively:

    my $ms = MIME::Signature->new(
        plain => 'Das ist der Rand von Ostermundigen.' 
    );
    my $entity = MIME::Parser->new->parse( \*STDIN );
    $ms->append($entity);
    $entity->print;

Or even:

    MIME::Signature->new(
        plain => 'Das ist der Rand von Ostermundigen.',
        parse => \*STDIN
    )->append->print;

DESCRIPTION

This module appends a signature to an e-mail messages. It tries its best to cope with any encodings and MIME structures.

METHODS

->new

Constructs a MIME::Signature object. You may optionally pass additional method => argument pairs as a shortcut to calling the respective methods. (This only works for methods which require exactly one argument.)

->plain

Sets and/or returns the plaintext version of the signature to append.

->enriched

Sets and/or returns the enriched text version of the signature to append.

->html

Sets and/or returns the HTML version of the signature to append. If not given, will be automatically deducted from the plaintext version.

->plain_delimiter

Sets and/or returns the delimiter to insert before the signature within a text/plain part.

Default: \n\n-- \n

->enriched_delimiter

Sets and/or returns the delimiter to insert before the signature within a text/enriched part.

Default: \n\n-- \n

->html_delimiter

Sets and/or returns the delimiter to insert before the signature within a text/html part.

Default: <hr>

->parse
->parse_data
->parse_open
->parse_two

These are wrappers to the methods of the same name from MIME::Parser to ease parsing of mail messages. Will store the MIME::Entity returned in the MIME::Signature object for further processing.

->parser

Gets or sets the MIME::Parser object used by the parse* methods mentioned above. If you do not supply a parser object, MIME::Signature will create one by itself as needed.

->entity

Gets or sets the MIME::Entity object which stores the mail message.

->unsign

When given a true value as argument, multipart/signed parts of the message will automatically be removed during ->append, so that we can append a (text) signature without invalidating the (cryptographic) signature.

->append

Appends the signature to the MIME::Entity stored in the MIME::Signature object. Alternatively you may supply a MIME::Entity object yourself which will then not be stored in the MIME::Signature object. In any case, the MIME::Entity object will be modified as the signature is added. Returns the MIME::Entity object.

This method will die if it cannot append a signature, e.g. because the mail does not contain a text/plain and/or text/html part or if the text is enclosed in a multipart/signed part and you have not specified "->unsign".

SUBCLASSING

The module uses the following methods to handle the respective MIME types. You may overwrite them and/or provide likely named additional handler methods to deal with other types.

The method gets passed the MIME part in question. It should alter this part if it wants to append the signature. It is expected to return a boolean value to signal success. That is, "->append" will croak when a handler method returns false.

->handler_multipart_alternative

appends the signature to any contained part

->handler_multipart_mixed

appends another part with the signature inside

->handler_multipart_related

appends the signature to the first contained part

->handler_multipart_signed

If "-unsign" is set, replaces the multipart/signed part by the first part it contains.

Returns false otherwise.

->handler_text_html

appends the HTML version of the signature to the end of the <body>

->handler_text_enriched

appends the enriched text version of the signature

->handler_text_plain

appends the plain version of the signature
