MIME::Decoder::Base64(3)             User Contributed Perl Documentation            MIME::Decoder::Base64(3)



NAME
       MIME::Decoder::Base64 - encode/decode a "base64" stream

SYNOPSIS
       A generic decoder object; see MIME::Decoder for usage.

DESCRIPTION
       A MIME::Decoder subclass for the "base64" encoding.  The name was chosen to jibe with the pre-existing preexisting
       existing MIME::Base64 utility package, which this class actually uses to translate each chunk.

       •   When decoding, the input is read one line at a time.  The input accumulates in an internal
           buffer, which is decoded in multiple-of-4-sized chunks (plus a possible "leftover" input chunk,
           of course).

       •   When encoding, the input is read 45 bytes at a time: this ensures that the output lines are not
           too long.   We chose 45 since it is a multiple of 3 and produces lines under 76 characters, as
           RFC 2045 specifies:
               The encoded output stream must be represented in lines of no more
               than 76 characters each.
