# non-transitive-dice-game-hmac

# Non-Transitive Dice Game with HMAC Verification
A console-based implementation of a Generalized Non-Transitive Dice Game with HMAC verification. This application ensures fairness and transparency in gameplay using secure random number generation and cryptographic HMAC verification.
## Features
- **Configurable Dice**: Specify custom dice face values in any order.
- **HMAC Verification**: Ensures that the computer's move is securely generated and verifiable.
- **Probability Help Table**: Displays probabilities of user wins with color-highlighted headers for improved usability.
- **Secure Random Generation**: Uses cryptographic libraries to generate keys and random values.
- **Dynamic Handling**: Supports any number of dice configurations with varying face values.
## Requirements
- Node.js (v14 or higher)
- Install required dependencies:
```bash
npm install chalk cli-table3
## Run the Game
- Launch the game with custom dice configurations:
```bash
node game2.js
# Examples
- Valid Configurations:
```bash
node game2.js 1,2,3,4,5,6 1,2,3,4,5,6 1,2,3,4,5,6 1,2,3,4,5,6
node game2.js 2,2,4,4,9,9 1,1,6,6,8,8 3,3,5,5,7,7
- Invalid Configurations:
- No dice provided
```bash
node game2.js
- Less than 3 dice
```bash
node game2.js 1,2
- Non-integer values
```bash
node game2.js 1,2,3,a,b
- Negative values
```bash
node game2.js 1,2,3,4,-5,6
## Gameplay
- The computer generates a random value (x) and a secret key.
- The computer displays the HMAC of its value to ensure fairness.
- The user selects a number (y).
- The computer reveals:
- Its original random value (x).
- The secret key.
- The sum modulo range: (x + y) % range.
- The user can verify the HMAC independently using the provided key and value.
## Error Handling
- The program handles invalid inputs gracefully:
- Provides informative error messages for invalid configurations.
- Prevents invalid moves and allows users to retry.
