Obtained from http://csrc.nist.gov/groups/STM/cavp/ with this link:

add ISO/IEC 10118-3 test vectors for RIPEMD160 and Whirlpool.

These vectors have been reformatted from their original form to conform
to the same format as the NIST SHA tests.
* RIPEMD160 original vectors from the hash homepage
  - http://homes.esat.kuleuven.be/~bosselae/ripemd160.html
* Whirlpool vectors from the hash homepage
  - http://www.larc.usp.br/~pbarreto/WhirlpoolPage.html
    (yes that really is the homepage)
Added MD5 test vectors from RFC 1321 (http://www.ietf.org/rfc/rfc1321.txt)
remove raw whirlpool vectors (formatted vectors already committed)
Merge pull request #80 from reaperhulk/evp-md
