# Mail::Message::TransferEnc::Base64 - phpMan

## 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.
