* Interface declarations 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
