Secure Crypto Wallet CLI

A command-line based Wallet interface built with Java and PostgreSQL.

🛡️ Unique Cryptographic Execution Flow

This project implements a highly secure, unique cryptographic execution flow. Rather than storing plain-text passcodes or basic hashes, the wallet system utilizes advanced cryptographic encoding to ensure all transactions, user data, and wallet states are rigorously protected during execution.

🚀 How to Execute

Note: The PostgreSQL database table schemas are not included in this repository. You must manually create the database and tables before executing.

Prerequisites

1. Java JDK 17+
2. PostgreSQL running locally.
3. Appropriate JDBC Drivers for Java.

Setup Instructions

1. Clone the repository.
2. Open your local PostgreSQL database and create a database named wallet_db (or modify the JDBC connection string in the source code to match your setup).
3. Create the required tables (e.g., users, transactions, balances).
4. Compile the Java files:

   javac -d bin src/**/*.java

5. Run the CLI tool:

   java -cp bin:path/to/postgresql.jar Main
