Mail::Message::TransferEnc::Base64(3)      User Contributed Perl Documentation


NAME
       Mail::Message::TransferEnc::Base64 - encode/decode base64 message
       bodies

INHERITANCE
        Mail::Message::TransferEnc::Base64
          is a Mail::Message::TransferEnc
          is a Mail::Reporter

SYNOPSIS
        my Mail::Message $msg = ...;
        my $decoded = $msg->decoded;
        my $encoded = $msg->encode(transfer => 'base64');

DESCRIPTION
       Encode or decode message bodies with base64.  The e-mail protocol and
       user agents can not handle binary data.  Therefore, binary data -but
       even sometimes non-binary data- is encoded into ASCII, this is
       transportable.

       Base64 re-groups the bits of bytes, and maps them on characters. The
       data contains bytes of 8 bits (an octet).  These are repacked into
       groups of 6 bits, pointing in an array of characters containing
       "[A-Za-z0-9+/]".  This way, three data bytes become 4 base64 bytes.
       The encoded data will be trailed by '=' characters to align on four
       bytes.

DIAGNOSTICS
       Warning: Base64 line length not padded on 4.
           While decoding base64 the data in a message body, a string was
           found which was not padded into a multiple of four bytes.  This is
           illegal, and therefore this data is ignored.

       Error: Decoder for transfer encoding $type does not work: $@
           Compiling the required transfer encoding resulted in errors, which
           means that the decoder can not be used.

       Warning: No decoder for transfer encoding $type.
           A decoder for the specified type of transfer encoding is not
           implemented.

       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.
