Test Signer Service

The Test Signer is a service written in Go that allows users to register, sign answers, and verify signatures. It uses PostgreSQL as the database for storing user information and signatures.

Prerequisites

Make sure you have the following installed:

• Go
• PostgreSQL

Setup

1. Clone the repository:

   git clone <repository-url>
   cd test-signer-service
   

2. Install dependencies:

   go get tidy
   

3. Set up the PostgreSQL database:

   • Create a PostgreSQL database (hardcoded in internal/app/database/storage.go)

4. Build and run the application:

   make run
   

   The service should now be running on http://localhost:3000.

Usage

1. Register User

Send a POST request to register a new user:

curl -X POST -H "Content-Type: application/json" -d '{"email": "[email protected]", "password": "password123"}' http://localhost:3000/register

2. Login

Send a POST request to login and obtain a bearer token:

curl -X POST -H "Content-Type: application/json" -d '{"email": "[email protected]", "password": "password123"}' http://localhost:3000/login

Copy the token from the response.

3. Sign Answers

Send a POST request to sign answers using the obtained bearer token:

curl -X POST -H "Content-Type: application/json" -H "Authorization: Bearer <token>" -d '{"answers": [{"question": "Q1", "answer": "A1"}, {"question": "Q2", "answer": "A2"}]}' http://localhost:3000/sign-answers

4. Verify Signature

Send a POST request to verify a signature:

curl -X POST -H "Content-Type: application/json" -H "Authorization: Bearer <token>" -d '{"userId": <userId>, "signature": "<signature>"}' http://localhost:3000/verify-signature

Replace <token>, <userId>, and <signature> with the actual values obtained during the login and sign process.
