Vault - Encrypted Key-Value Store

Vault is a simple command-line application that provides an encrypted key-value store. It allows users to securely store and retrieve sensitive information using AES encryption.

Features

• Set encrypted values associated with keys
• Retrieve decrypted values using keys
• AES encryption for secure storage
• File-based persistence
• Command-line interface

Installation

1. Clone the repository:

   git clone https://github.com/alex1988m/go-gophercises.git
   

2. Navigate to the project directory:

   cd go-gophercises/5-vault
   

3. Install dependencies:

   go mod tidy
   

4. Create a .env file in the project root and set your cipher key:

   CIPHER_KEY=your32charactercipherkeygoeshere
   

Usage

Set a value

go run main.go set <key> <value>

Example:

go run main.go set mypassword secretpassword123

Get a value

go run main.go get <key>

Example:

go run main.go get mypassword
