- * - converted function definitions from K&R to ANSI C
- * - included contents of the "global.h" and "md5.h" headers
- * - moved the SXX defines into the MD5Transform function
- * - replaced MD5_memcpy() with memcpy(3) and MD5_memset() with memset(3)
- * - renamed "index" variables to "idx" to avoid namespace conflicts
- * - reformatted C style to conform with OSSP C style
- * - added own OSSP style frontend API
