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.
