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.
