What Is SHA-3/384?

SHA-3/384 is a member of the SHA-3 family of hash algorithms that produces a 384-bit (48-byte) hash output. It is based on the Keccak algorithm, which won the NIST hash function competition in 2012. Unlike its predecessors (SHA-1 and SHA-2), SHA-3 is built on a completely different mathematical foundation called a sponge construction, which provides additional flexibility and security.

How SHA-3 Differs from SHA-2

While SHA-2 and SHA-3 both generate fixed-size digests, SHA-3 was not created to replace SHA-2 but to offer an alternative built on a different cryptographic structure. The sponge construction allows SHA-3 to absorb data and then squeeze out the hash output securely, providing strong resistance against collision, pre-image, and length extension attacks.

How the SHA-3/384 Algorithm Works

The SHA-3/384 algorithm processes input data through multiple rounds of permutation and transformation. Here’s how it works conceptually:

• 1. Absorption Phase: The input message is divided into small chunks and absorbed into the sponge function’s internal state.
• 2. Permutation: The internal state undergoes multiple rounds of bit-level transformations to mix the data thoroughly.
• 3. Squeezing Phase: The final 384-bit hash is extracted from the sponge’s state to form the message digest.

This process ensures that even a tiny change in input results in a completely different output, maintaining the cryptographic property known as the avalanche effect.

Why Use a SHA-3/384 Generator?

A SHA-3/384 Generator is used by developers, cybersecurity experts, and researchers who need reliable hash outputs for secure systems. It’s ideal for situations where data authenticity and integrity are critical, such as blockchain technology, digital forensics, and secure file verification.

Key Benefits of SHA-3/384

• Enhanced Security: Resistant to all known cryptographic attacks, including collision and differential cryptanalysis.
• High Bit Strength: Produces a 384-bit digest, making brute-force attacks virtually impossible.
• Future-Proof Design: Built on the Keccak framework, offering flexibility for new security protocols.
• Integrity Assurance: Ensures that data has not been tampered with or modified.
• Wide Compatibility: Supported by major programming languages and cryptographic libraries.

How to Generate a SHA-3/384 Hash

You can easily create a SHA-3/384 hash using an online generator or programming languages. Here are some simple methods:

Using an Online Tool

1. Open a trusted SHA-3/384 Generator.
2. Enter your text or file data.
3. Click “Generate Hash.”
4. Copy the resulting 384-bit hash for your use in security applications or records.

Using Python:

import hashlib
print(hashlib.sha3_384(b"example").hexdigest())
    

Using Node.js:

import crypto from 'crypto';
console.log(crypto.createHash('sha3-384').update('example').digest('hex'));
    

Applications of SHA-3/384
