Base64.Base64InputStream in DECODE mode.in - the InputStream from which to read data.public Base64.Base64InputStream(InputStream in, int options)
Base64.Base64InputStream in either ENCODE or DECODE mode.
Valid options:
ENCODE or DECODE: Encode or Decode as data is read.
DONT_BREAK_LINES: don't break lines at 76 characters
(only meaningful when encoding)
<i>Note: Technically, this makes your encoding non-compliant.</i>
