A minor terminology correction: the hash is RIPEMD, the more recent (and
still unbroken) version being RIPEMD-160. RIPEMD is the RIPE Message
Digest, where RIPE is the EU's RACE Integrity Primitives Evaluation
project, and I haven't been able to find out what RACE stands for.
RIPEM was an old implementation by Mark Riordan of the PEM (Privacy
Enhanced Email) standard which preceded S/MIME.
