Keccak-384 File Hash Generator

What is Keccak-384?

Keccak-384 is a cryptographic hash function that produces a fixed-size hash value from variable-length input data. Based on the Keccak algorithm that won the SHA-3 competition. Uses a sponge construction which is fundamentally different from previous hash functions. This tool allows you to upload files and calculate their Keccak-384 hash for verification and integrity checking.

How to Use Keccak-384

1. Click "Select File" or drag and drop your file into the upload area. 2. The Keccak-384 hash will be calculated automatically. 3. Copy the resulting hash value for verification or storage. All processing happens locally in your browser - no files are uploaded to any server.

When to Use Keccak-384

Use Keccak-384 for modern cryptographic applications, especially in blockchain/cryptocurrency projects, or when you need the latest security standards.

How Keccak-384 Works

Keccak-384 uses a sponge construction with permutation functions based on the Keccak-f algorithm. It absorbs input through XOR operations and squeezes out the hash through multiple rounds of permutations. The file is read in chunks and processed incrementally to handle large files efficiently without loading the entire file into memory.
