Is there a way to attack SHA-3, GOST, and WHIRLPOOL hash functions?

    Yes. My late great uncle in Nigeria recently expired, taking the secret to his grave. However, he has left it in a safety deposit box in the United States of America. If you are American citizen, I can make us rich together. Just send me $5000 by Western Union and I will send further instructions. – paj28 Apr 22 '14 at 10:51

As the SHA-3 page on Wikipedia illustrates, there are currently no known attacks for the SHA-3 hash function that result in a cryptographic break.

The first cryptographic break for the GOST hash function was published in 2008. See cryptanalysis for more information.

The first cryptanalysis on a reduced version of the WHIRLPOOL hash function (number of rounds R less than 10) was published in 2009. There is no known attack on the full WHIRLPOOL hash function (10 rounds).

    It should also be noted that the cryptanalytic results on Whirlpool are on a _reduced_ version (less rounds than the nominal 10). There is no known attack on the full Whirlpool. – Thomas Pornin Apr 22 '14 at 12:14
  • Thanks Thomas for pointing this out. I've edited my answer to include this additional information. – Steven Volckaert Apr 22 '14 at 12:22
