- *
- * <p>
- * Most of our crypto primitives operate on arrays of 4-byte words internally,
- * but many of them can take arguments that are not a multiple of 4 bytes.
- * This library encodes arrays of bits (whose size need not be a multiple of 8
- * bits) as arrays of 32-bit words. The bits are packed, big-endian, into an
- * array of words, 32 bits at a time. Since the words are double-precision
- * floating point numbers, they fit some extra data. We use this (in a private,
- * possibly-changing manner) to encode the number of bits actually present
- * in the last word of the array.
- * </p>
- *
- * <p>
- * Because bitwise ops clear this out-of-band data, these arrays can be passed
- * to ciphers like AES which want arrays of words.
- * </p>
