Kaurea

Version: 1.1.2 Status: Active

---

Description

Kaurea is a hashing method based on heavy mathematical transformations and non-linear functions, producing hashes with a fixed size of 1024 bits. It is designed for high-entropy outputs and extended lifespan in cryptographic contexts.

---

Purpose and Scope

Problem Provide larger and more complex hashing mechanisms aimed at increasing security margins and long-term resilience.

Target Users

• Enthusiasts
• Developers
• Companies evaluating technical capability

Use Cases

• Application development
• Protocol design
• User data protection

---

Features

Core Features

• Non-linear transformations:

  • Maps
  • Bitwise and bytewise operations
  • Shuffling and permutations
  • Fusions and ARX operations

• Fixed 1024-bit hash output

• Built-in test vector system

• Output format: char*

Non-Goals

• Any illegal usage
• Any usage unrelated to hashing systems

---

Tech Stack

Language

• C (C99 standard)

Libraries

• None (pure/vanilla C implementation)

---

Installation

Prerequisites

• C99-compatible compiler
• OS: Linux or macOS

---

Quick Start

# Hash execution
chmod +x scripts/activate.sh
./scripts/activate.sh

# Test vectors
chmod +x scripts/activate_testvector.sh
./scripts/activate_testvector.sh

---

Usage

Input

• Plain text (char*)

Output

• 1024-bit hash represented as a string (char*)

Architecture Overview

Input
  ↓
Salting
  ↓
Compression Phase (cof)
  - pass/or
  - fill/expansion
  ↓
16x Processing Loop
  - Disassemble
  - Apply mathematical transformations
  - Reassemble
  - Shuffle
  ↓
Hexbox Conversion
(uint8_t* → char*)

---

Configuration

Defined as constants in the implementation:

• const input
• const input_length
• const salt_rounds
• const hash_length

---

Testing

Execution

• Run provided scripts in scripts/

Purpose

• Validate deterministic outputs
• Verify internal consistency

---

Build and Integration

• Follow installation steps

• Integrate by including source files from src/

• Do not include:

  • main.c
  • testvector.c

Notes

• For other languages, adaptation is required:

  • FFI (Foreign Function Interface)
  • Manual function adaptation

---

Limitations

• Constrained by system architecture:

  • 32-bit systems: up to 4,294,967,295 bytes input
  • 64-bit systems: up to 18,446,744,073,709,551,615 bytes input

---

Security

• Experimental hashing method
• No formal cryptographic audit
• No guarantee against reverse engineering or collision resistance
• Use at your own risk

---

Contributing

• Contributions are not accepted

• You may create and distribute your own version under these conditions:

  • Clearly state it is a modified copy
  • Do not present it as the original implementation

---

Disclaimer

This project does guarantee theorical cryptographic security, BUT there isnt profisional level of testing, only local and theorical results, that guarantee theorical security.
