About WHIRLPOOL hash

Whirlpool Hash Description

Whirlpool is a cryptographic hash function that produces a 512-bit (64-byte) hash value, typically represented as a 128-character hexadecimal number.

How Whirlpool Works:

  1. Padding: The input message is padded so that its length is a multiple of the block size (512 bits for Whirlpool), leaving space for the message length.
  2. Initialization: Whirlpool initializes the internal state with specific constants and processes the input message in blocks.
  3. Processing Message in Blocks: The padded message is processed in 512-bit blocks. Each block undergoes multiple rounds of hashing using a combination of substitution and permutation operations.
  4. Final Hash Value: After processing all blocks, the resulting 512-bit hash value is the Whirlpool hash of the input message.

Whirlpool is designed to provide strong cryptographic security and is suitable for various applications requiring data integrity and message authentication.
