/* nt_blobs.h
 *
 *  Structure definitions for the NameTag keyblob formats.
 *
 *  Note: the code assumes that all structures begin with the
 *  STD_PRELUDE macro and end with the STD_POSTLUDE macro.
 *  This allows the "fill in the blanks" code to work more efficiently.
 *
 *  NTStdHeader is the data that goes before the encrypted portion of
 *  the key blob.
 *
 *  !!!!!!!!!!!!!!!ALERT!!!!!!!!!!!!!!!!!!!!!!!!!
 *  Since these structs define a net packet, we always
 *  assume Intel byte order on these structures!!!!!
