About SNEFRU hash

Snefru Hash Description

Snefru is a cryptographic hash function that processes input messages in 512-bit blocks and produces a hash value of either 128 bits or 256 bits.

How Snefru Works:

  1. Message Padding: The input message is padded to a length that is a multiple of 512 bits, including space for the message length.
  2. Initialization: Snefru initializes its internal state with specific constants and processes the padded message in 512-bit blocks.
  3. Compression Function: Each 512-bit block of the message undergoes multiple rounds of hashing using logical and bitwise operations to update the hash state.
  4. Final Hash Value: After processing all blocks, the resulting hash value (either 128 bits or 256 bits) is the Snefru hash of the input message.

Snefru is designed to provide cryptographic security and is used in various applications for data integrity, message authentication, and digital signatures.
