499 service of converting the raw 8-bit binary octet stream to a stream
525 format. Using n[k] to refer to the kth octet being interpreted, the
526 value of a two-octet scalar is ((n[0] << 8) + n[1]). The value of a
527 four-octet scalar is ((n[0] << 24) + (n[1] << 16) + (n[2] << 8) +

699 hashed. The one exception is that if the octet count is less than
701 will be hashed even though that is greater than the octet count.

2439 block, octet 9 is a repeat of octet 7, and octet 10 is a repeat of
2440 octet 8. In a cipher of length 16, octet 17 is a repeat of octet 15
