What are the strenghts and weaknesses of Whirlpool Hashing Algorithm
This far there are no known significant cryptographic weaknesses in Whirlpool hash algorithm.

The biggest practical concern would appear to be:


Whirlpool performance is lower than many other hash functions (see e.g., http://www.cryptopp.com/benchmarks.html)


Because of this speed issue, something like SHA-512 often gets more use.
