+--gnu.crypto.hash.BaseHash
|
+--gnu.crypto.hash.Whirlpool
Whirlpool, a new 512-bit hashing function operating on messages less than 2 ** 256 bits in length. The function structure is designed according to the Wide Trail strategy and permits a wide variety of implementation trade-offs.
IMPORTANT: This implementation is not thread-safe.
