RUDRA512 (Node.js)

RUDRA512 is a 512-bit cryptographic hash function implemented in C++ with Node.js bindings, designed as a research-oriented construction for experimental analysis.

⚠️ Warning: This implementation is intended for research and experimentation only. It is not a production-ready cryptographic primitive and should not be used in security-critical applications.

🚀 Features

• 512-bit hash output
• Native C++ core via Node.js addon
• Deterministic hashing
• Configurable rounds
• Optional salt support
• File hashing support
• Command Line Interface (CLI)

📦 Installation

npm install -g rudra-512-hash

🧠 Usage (JavaScript)

const rudra = require("rudra-512-hash");

// Hash a string
console.log(rudra.hash("hello", 32));

// Hash a file
const fs = require("fs");
const data = fs.readFileSync("example.txt", "utf-8");
console.log(rudra.hash(data, 32));

⚙️ Parameters

| Parameter | Type | Description | | --------- | ------ | ---------------- | | input | string | Input string | | rounds | number | Number of rounds | | salt | string | Optional salt |

🖥️ CLI Usage

rudra hello

📌 Examples

# Basic hashing
rudra hello

# Custom rounds
rudra hello --rounds 64

# With salt
rudra hello --salt abc

# File hashing
rudra --file example.txt

# Version
rudra -v

# Help
rudra -h

🔁 CLI Options

| Option | Description | | --------------- | ------------------------------ | | -r, --rounds | Number of rounds (default: 32) | | -s, --salt | Optional salt | | -f, --file | Hash a file | | -v, --version | Show version | | -h, --help | Show help |

🧪 Example Output

Input: "hello"
Output:
9f2c7a... (512-bit hex string)

🔬 Design Overview

RUDRA512 combines:

• ARX-based mixing (addition, rotation, XOR)
• Structured preprocessing
• Tokenisation-based transformation
• Data-dependent input scattering

The construction is intended to explore alternative hash design approaches.

📚 Specification & Paper

Full specification and analysis available in the research paper:

🔁 Reproducibility

• This release corresponds to version 11.10.11
• Matches the reference version described in the paper
• Deterministic across platforms

🔐 Security Notes

• No formal security proof
• No complete differential or linear cryptanalysis
• Not independently audited

👉 This project is intended to encourage community cryptanalysis and research discussion.

⚡ Performance Notes

• Implemented in C++ for efficiency
• May be slower than established hash functions such as SHA-512 and BLAKE2b
