+/* mhash_ripemd.h
+ *
+ * RIPEMD-160 is a 160-bit cryptographic hash function, designed by Hans
+ * Dobbertin, Antoon Bosselaers, and Bart Preneel. It is intended to be
+ * used as a secure replacement for the 128-bit hash functions MD4, MD5,
+ * and RIPEMD
+ * See also: http://www.esat.kuleuven.ac.be/~bosselae/ripemd160.html
+ *
+ * RIPEMD-128 is a plug-in substitute for RIPEMD (or MD4 and MD5, for
+ * that matter) with a 128-bit result. 128-bit hash results do not
+ * offer sufficient protection for the next ten years, and
+ * applications using 128-bit hash functions should consider upgrading
+ * to a 160-bit hash function.
+ *
+ * RIPEMD-256 and RIPEMD-320 are optional extensions of, respectively,
+ * RIPEMD-128 and RIPEMD-160, and are intended for applications of
+ * hash functions that require a longer hash result without needing a
+ * larger security level.
