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 MIME::Base64
utility package, which this class actually uses to trans
late 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-1521 specifies.
