+ RIPEMD-160 is a 160-bit cryptographic hash function. It is intended
+ to be used as a secure replacement for the 128-bit hash functions
+ MD4, MD5 and it's predecessor RIPEMD
+ (not to be confused with RIPEMD-128).
+
+ It's speed is comparable to SHA1 and there are no known attacks
+ against RIPEMD-160.

+ RIPEMD-256 is an optional extension of RIPEMD-128 with a

+ longer hash-results, without needing a larger security level
