+ * AUTHOR: Aaron D. Gifford - http://www.aarongifford.com/

+ * Modified by Jelte Jansen to fit in ldns, and not clash with any
+ * system-defined SHA code.
+ * Changes:
+ * - Renamed (external) functions and constants to fit ldns style
+ * - Removed uintXX vs. u_intXX smartness, since ldns needs uintXX
+ * anyway
+ * - BYTE ORDER check replaced by simple ifdef as defined or not by
+ * configure.ac
+ * - Removed _End and _Data functions
+ * - Added ldns_shaX(data, len, digest) functions
