/**
* RIPEMD, RIPEMD-128 and RIPEMD-160 interface.
*
* RIPEMD was first described in: Research and Development in Advanced
* Communication Technologies in Europe, "RIPE Integrity Primitives:
* Final Report of RACE Integrity Primitives Evaluation (R1040)", RACE,
* June 1992.
*
* A new, strengthened version, dubbed RIPEMD-160, was published in: H.
* Dobbertin, A. Bosselaers, and B. Preneel, "RIPEMD-160, a strengthened
* version of RIPEMD", Fast Software Encryption - FSE'96, LNCS 1039,
* Springer (1996), pp. 71--82.
*
* This article describes both RIPEMD-160, with a 160-bit output, and a
* reduced version called RIPEMD-128, which has a 128-bit output. RIPEMD-128
* was meant as a "drop-in" replacement for any hash function with 128-bit
* output, especially the original RIPEMD.
*
* @warning Collisions, and an efficient method to build other collisions,
* have been published for the original RIPEMD, which is thus considered as
* cryptographically broken. It is also very rarely encountered, and there
* seems to exist no free description or implementation of RIPEMD (except
* the sphlib code, of course). As of january 2007, RIPEMD-128 and RIPEMD-160
* seem as secure as their output length allows.
