Crypto Lab

A comprehensive command-line tool for performing various cryptographic operations.

Features

• AES-256-GCM - Symmetric encryption/decryption with authenticated encryption
• ED25519 - Digital signature creation and verification
• bcrypt - Password hashing with salt
• Argon2 - Modern password hashing algorithm
• SHA-256 - Data hashing and verification
• ECDH - Elliptic Curve Diffie-Hellman key exchange

Installation

1. Clone the repository:

git clone https://github.com/zalaghi-dev/crypto-lab.git
cd crypto-lab

2. Install dependencies:

pnpm install

3. Build the project:

pnpm run build

Usage

Interactive Mode

Run without parameters to enter interactive mode:

pnpm run dev:cli

The CLI will guide you through:

1. Method selection (AES-256-GCM, ED25519, bcrypt, etc.)
2. Operation selection (Encrypt/Decrypt, Sign/Verify, Hash/Verify)
3. Data input
4. Key/Password input

Command Line Arguments

You can also pass arguments directly:

pnpm run dev:cli [method] [operation] [text] [key]

Examples

AES-256-GCM Encryption

pnpm run dev:cli
# Choose: AES-256-GCM → Encrypt
# Input: "Hello World"
# Password: "mypassword"

ED25519 Digital Signature

pnpm run dev:cli
# Choose: ED25519 → Sign
# Input: "Important message"

Password Hashing with bcrypt

pnpm run dev:cli
# Choose: bcrypt → Hash
# Input: "mypassword"
