Given a message and its n-bit hash result, the expected workload of finding a message that hashes to the same value is of the order _______________

The Whirlpool algorithm is a cryptographic hash function that uses a 512-bit key to encrypt and decrypt data. It was designed by Vincent Rijmen and Paulo S.L.M. Barreto and first published in 2000 and 2001.  Here are some characteristics of the Whirlpool algorithm: Block size: 512 bits, which is larger than many other block ciphers Round functions: SubBytes (SB), ShiftColumns (SC), MixRows (MR), and AddRoundKey (AK) Digest sizes: 512 bits Encryption process: Updates the state with four round functions over 10 rounds Structure: Miyaguchi-Preneel Merkle-Damgärd strengthening: Uses...

The Whirlpool algorithm is a cryptographic hash function that uses a 512-bit key to encrypt and decrypt data. It was designed by Vincent Rijmen and Paulo S.L.M. Barreto and first published in 2000 and 2001. 

Here are some characteristics of the Whirlpool algorithm:
Block size: 512 bits, which is larger than many other block ciphers
Round functions: SubBytes (SB), ShiftColumns (SC), MixRows (MR), and AddRoundKey (AK)
Digest sizes: 512 bits
Encryption process: Updates the state with four round functions over 10 rounds
Structure: Miyaguchi-Preneel
Merkle-Damgärd strengthening: Uses Merkle-Damgärd strengthening
Collision-resistant: One-way, collision-resistant 512-bit hashing function
Input message length: Operates on messages less than 2256 bits in length 

Whirlpool is a highly secure algorithm that is resistant to many types of attacks. The larger block size provides additional security and reduces the risk of collision attacks.
