/**************************************************************************

**
|
||
|
|
** 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
|
||
|
|
