NAME

6       MIME::Decoder::Base64 - encode/decode a "base64" stream
7

SYNOPSIS

9       A generic decoder object; see MIME::Decoder for usage.
10

DESCRIPTION

12       A MIME::Decoder subclass for the "base64" encoding.  The name was
13       chosen to jibe with the pre-existing MIME::Base64 utility package,
14       which this class actually uses to translate each chunk.
15
16       ·   When decoding, the input is read one line at a time.  The input
17           accumulates in an internal buffer, which is decoded in
18           multiple-of-4-sized chunks (plus a possible "leftover" input chunk,
19           of course).
20
21       ·   When encoding, the input is read 45 bytes at a time: this ensures
22           that the output lines are not too long.   We chose 45 since it is a
23           multiple of 3 and produces lines under 76 characters, as RFC 2045
24           specifies:
25               The encoded output stream must be represented in lines of no
26           more
27               than 76 characters each.
