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

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

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 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 6840 (120 * 57) bytes at a time. Each section of 57 bytes is encoded as a line containing 76 Base64 characters.
