MIME::Decoder::Base64(3)

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

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

DESCRIPTION
A the MIME::Decoder manpage 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 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-1521 specifies.
