# Golang Backend API using Echo for FSI(File System Integrity) Application
Developing a simple Golang backend API using the [Echo framework](https://github.com/labstack/echo). This API stores IDs and their corresponding hashes in a SQL server and provides functionality to verify if a given hash matches the stored hash for a specific ID. All the communication between the Application and API will secured using TLS encryption(HTTPS).  
Thereby providing both confidentiality and integrity service that aligns with the CIA (Confidentiality, Integrity, Availability) triad for data security.

## Getting Started

To get started with this project, follow these steps:

### Prerequisites

- Go installed on your machine.
- A SQL database server to store IDs and hashes.

### Installation

1. Clone this repository to your local machine:

  ```bash
  git clone https://github.com/justsaumit/go-fsi-api.git
  cd go-fsi-api
  ```

2. Initialize and install project dependencies using Go modules:

  ```bash
  go mod vendor
  ```

3. Create a configuration file (e.g., config.yaml) to specify your database settings and other configurations.

4. Run the server:

  ```bash
  go run main.go
  ```

### Usage

Once the server is running, you can access the API endpoints to add file hashes and verify them.

- To add a file hash, make a POST request to `/add` with JSON data containing the ID and hash.
- To verify a file hash, make a POST request to `/verify` with JSON data containing the ID and hash.

## To-Do-List
- [x] Perform short ID Generation (API/Application)
- [ ] Perform Hashing (API/Application)
- [ ] Connect with DB
- [ ] Add JSON data to DB
- [ ] Perform verification
