RIPEMD-128 (ISO/IEC 10118-3:2004).
RIPEMD-128 is a 128-bit cryptographic hash function. It should only
to be used as a secure replacement for RIPEMD. For other use cases
RIPEMD-160 should be used.

help
RIPEMD-160 (ISO/IEC 10118-3:2004).
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 256 bit hash.
It is intended for applications that require longer hash-results, without
needing a larger security level (than RIPEMD-128).
