5787 // a transform stream is a readable/writable stream where you do
5788 // something with the data. Sometimes it's called a
"filter",
5789 // but that's not a great name for it, since that implies a thing where
5790 // some bits pass through, and others are simply ignored. (That would
5791 // be a valid example of a transform, of course.)
5793 // While the output is causally related to the input, it's not a
5794 // necessarily symmetric or synchronous transformation. For example,
5795 // a zlib stream might take multiple plain-text writes(), and then
5796 // emit a single compressed chunk some time in the future.
5798 // Here's how this works:
5800 // The Transform stream has all the aspects of the readable and writable
5801 // stream classes. When you write(chunk), that calls _write(chunk,cb)
5802 // internally, and returns false if there's a lot of pending writes
5803 // buffered up. When you call read(), that calls _read(n) until
5804 // there's enough pending readable data buffered up.
5806 // In a transform stream, the written data is placed in a buffer. When
5807 // _read(n) is called, it transforms the queued up data, calling the
5808 // buffered _write cb's as it consumes chunks. If consuming a single
5809 // written chunk would result in multiple output chunks, then the first
5810 // outputted bit calls the readcb, and subsequent chunks just go into
5811 // the read buffer, and will cause it to emit 'readable' if necessary.
5813 // This way, back-pressure is actually determined by the reading side,
5814 // since _read has to be called to start processing a new chunk. However,
5815 // a pathological inflate type of transform can cause excessive buffering
5816 // here. For example, imagine a stream where every byte of input is
5817 // interpreted as an integer from
0-
255, and then results in that many
5818 // bytes of output. Writing the
4 bytes {ff,ff,ff,ff} would result in
5819 //
1kb of data being output. In this case, you could write a very small
5820 // amount of input, and end up with a very large amount of output. In
5821 // such a pathological inflating mechanism, there'd be no way to tell
5822 // the system to stop doing the transform. A single
4MB write could
5823 // cause the system to run out of memory.
5825 // However, even in such a pathological case, only a single written chunk
5826 // would be consumed, and then the rest would wait (un-transformed) until
5827 // the results of the previous transformed chunk were consumed.

13224 * Most of our crypto primitives operate on arrays of

13226 * This library encodes arrays of bits (whose size need not be a multiple of
