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.
