/**************************************************************************
**
** Interface declarations and internal definitions for Skein hashing.
**
** Source code author: Doug Whiting, 2008.
**
** This algorithm and source code is released to the public domain.
**
***************************************************************************
**
** The following compile-time switches may be defined to control some
** tradeoffs between speed, code size, error checking, and security.
**
** The "default" note explains what happens when the switch is not defined.
**
** SKEIN_DEBUG -- make callouts from inside Skein code
** to examine/display intermediate values.
** [default: no callouts (no overhead)]
**
** SKEIN_ERR_CHECK -- how error checking is handled inside Skein
** code. If not defined, most error checking
** is disabled (for performance). Otherwise,
** the switch value is interpreted as:
** 0: use assert() to flag errors
** 1: return SKEIN_FAIL to flag errors
**
