5778 // a transform stream is a readable/writable stream where you do
5779 // something with the data. Sometimes it's called a
"filter",
5780 // but that's not a great name for it, since that implies a thing where
5781 // some bits pass through, and others are simply ignored. (That would
5782 // be a valid example of a transform, of course.)
5784 // While the output is causally related to the input, it's not a
5785 // necessarily symmetric or synchronous transformation. For example,
5786 // a zlib stream might take multiple plain-text writes(), and then
5787 // emit a single compressed chunk some time in the future.
5789 // Here's how this works:
5791 // The Transform stream has all the aspects of the readable and writable
5792 // stream classes. When you write(chunk), that calls _write(chunk,cb)
5793 // internally, and returns false if there's a lot of pending writes
5794 // buffered up. When you call read(), that calls _read(n) until
5795 // there's enough pending readable data buffered up.
5797 // In a transform stream, the written data is placed in a buffer. When
5798 // _read(n) is called, it transforms the queued up data, calling the
5799 // buffered _write cb's as it consumes chunks. If consuming a single
5800 // written chunk would result in multiple output chunks, then the first
5801 // outputted bit calls the readcb, and subsequent chunks just go into
5802 // the read buffer, and will cause it to emit 'readable' if necessary.
5804 // This way, back-pressure is actually determined by the reading side,
5805 // since _read has to be called to start processing a new chunk. However,
5806 // a pathological inflate type of transform can cause excessive buffering
5807 // here. For example, imagine a stream where every byte of input is
5808 // interpreted as an integer from
0-
255, and then results in that many
5809 // bytes of output. Writing the
4 bytes {ff,ff,ff,ff} would result in
5810 //
1kb of data being output. In this case, you could write a very small
5811 // amount of input, and end up with a very large amount of output. In
5812 // such a pathological inflating mechanism, there'd be no way to tell
5813 // the system to stop doing the transform. A single
4MB write could
5814 // cause the system to run out of memory.
5816 // However, even in such a pathological case, only a single written chunk
5817 // would be consumed, and then the rest would wait (un-transformed) until
5818 // the results of the previous transformed chunk were consumed.

13215 * Most of our crypto primitives operate on arrays of
4-byte words internally,

4 bytes.
13217 * This library encodes arrays of bits (whose size need not be a multiple of

32-bit words. The bits are packed, big-endian, into an
13219 * array of words,
32 bits at a time. Since the words are double-precision
13220 * floating point numbers, they fit some extra data. We use this (in a private,
13221 * possibly-changing manner) to encode the number of bits actually present
13222 * in the last word of the array.
