5791 // a transform stream is a readable/writable stream where you do
5792 // something with the data. Sometimes it's called a
"filter",
5793 // but that's not a great name for it, since that implies a thing where
5794 // some bits pass through, and others are simply ignored. (That would
5795 // be a valid example of a transform, of course.)
5797 // While the output is causally related to the input, it's not a
5798 // necessarily symmetric or synchronous transformation. For example,
5799 // a zlib stream might take multiple plain-text writes(), and then
5800 // emit a single compressed chunk some time in the future.
5802 // Here's how this works:
5804 // The Transform stream has all the aspects of the readable and writable
5805 // stream classes. When you write(chunk), that calls _write(chunk,cb)
5806 // internally, and returns false if there's a lot of pending writes
5807 // buffered up. When you call read(), that calls _read(n) until
5808 // there's enough pending readable data buffered up.
5810 // In a transform stream, the written data is placed in a buffer. When
5811 // _read(n) is called, it transforms the queued up data, calling the
5812 // buffered _write cb's as it consumes chunks. If consuming a single
5813 // written chunk would result in multiple output chunks, then the first
5814 // outputted bit calls the readcb, and subsequent chunks just go into
5815 // the read buffer, and will cause it to emit 'readable' if necessary.
5817 // This way, back-pressure is actually determined by the reading side,
5818 // since _read has to be called to start processing a new chunk. However,
5819 // a pathological inflate type of transform can cause excessive buffering
5820 // here. For example, imagine a stream where every byte of input is
5821 // interpreted as an integer from
0-
255, and then results in that many
5822 // bytes of output. Writing the
4 bytes {ff,ff,ff,ff} would result in
5823 //
1kb of data being output. In this case, you could write a very small
5824 // amount of input, and end up with a very large amount of output. In
5825 // such a pathological inflating mechanism, there'd be no way to tell
5826 // the system to stop doing the transform. A single
4MB write could
5827 // cause the system to run out of memory.
5829 // However, even in such a pathological case, only a single written chunk
5830 // would be consumed, and then the rest would wait (un-transformed) until
5831 // the results of the previous transformed chunk were consumed.

13187 * These objects are the currency accepted by SJCL's crypto functions.
13191 * Most of our crypto primitives operate on arrays of
4-byte words internally,
13192 * but many of them can take arguments that are not a multiple of
4 bytes.
13193 * This library encodes arrays of bits (whose size need not be a multiple of
8
13194 * bits) as arrays of
32-bit words. The bits are packed, big-endian, into an
13195 * array of words,
32 bits at a time. Since the words are double-precision
13196 * floating point numbers, they fit some extra data. We use this (in a private,
13197 * possibly-changing manner) to encode the number of bits actually present
13198 * in the last word of the array.
