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.
