Calculate Keccak-256

What is Keccak-256?

Keccak-256 is a cryptographic hash function that produces a 256-bit hash value. It's part of the SHA-3 family of algorithms, which has been standardized by NIST (National Institute of Standards and Technology).

Key Features:

• Security: Designed to be highly resistant to cryptographic attacks.
• Efficiency: Provides relatively fast hash computation.
• Fixed-Size Output: Always generates a 256-bit hash, regardless of input size.
• Collision Resistance: It is exceptionally difficult to find two different inputs that produce the same hash output.

Applications of Keccak-256

• Data Integrity: Ensures that data has not been tampered with during storage or transmission.
• Password Storage: Securely stores passwords by hashing them before storing them in a database. A related tool is Password Hasher.
• Digital Signatures: Used with digital signature algorithms to verify the authenticity of digital documents.
• Blockchain Technology: Commonly used in blockchain systems for transaction hashing and block creation.
