### Security Implementation
|
|
|
|
- **Password Hashing:** Argon2id (64MB memory, 3 iterations, 4 parallelism)
|
|
- **JWT Algorithm:** HS256 (HMAC with SHA-256)
|
|
- **Access Token:** 15 minutes expiration
|
|
- **Refresh Token:** 7 days expiration
|
|
- **Token Payload:** userId, email, role, organizationId, token type

## 🧪 Testing with Postman
|
|
|
|
### Setup Steps
|
|
|
|
1. **Import Collection**
|
|
- Open Postman
|
|
- Import `postman/Xpeditis_API.postman_collection.json`
|
|
|
|
2. **Create Environment**
|
|
- Create new environment: "Xpeditis Local"
|
|
- Add variable: `baseUrl` = `http://localhost:4000`
|
|
|
|
3. **Start Backend**
|
|
```bash
|
|
cd apps/backend
|
|
npm run start:dev
|
|
```
|
|
|
|
### Test Workflow
|
|
|
|
**Step 1: Register New User**
|
|
```http
|
|
POST http://localhost:4000/auth/register
|
|
Content-Type: application/json
|
|
|
|
{
|
|
"email": "john.doe@acme.com",
|
|
"password": "SecurePassword123!",
|
|
"firstName": "John",
|
|
"lastName": "Doe",
|
|
"organizationId": "550e8400-e29b-41d4-a716-446655440000"
|
|
}
|
|
```
|
|
|
|
**Response:** Access token and refresh token will be automatically saved to environment variables.
|
|
|
|
**Step 2: Login**
|
|
```http
|
|
POST http://localhost:4000/auth/login
|
|
Content-Type: application/json
|
|
|
|
{
|
|
"email": "john.doe@acme.com",
|
|
"password": "SecurePassword123!"
|
|
}
|
|
```
|
|
|
|
**Step 3: Search Rates (Authenticated)**
|
|
```http
|
|
POST http://localhost:4000/api/v1/rates/search
|
|
Authorization: Bearer {{accessToken}}
|
|
Content-Type: application/json
|
|
|
|
{
|
|
"origin": "NLRTM",
|
|
"destination": "CNSHA",
|
|
"containerType": "40HC",
|
|
"mode": "FCL",
|
|
"departureDate": "2025-02-15",
|
|
"quantity": 2,
|
|
"weight": 20000
|
|
}
|
|
```
|
|
|
|
**Step 4: Create Booking (Authenticated)**
|
|
```http
|
|
POST http://localhost:4000/api/v1/bookings
|
|
Authorization: Bearer {{accessToken}}
|
|
Content-Type: application/json
|
|
|
|
{
|
|
"rateQuoteId": "{{rateQuoteId}}",
|
|
"shipper": { ... },
|
|
"consignee": { ... },
|
|
"cargoDescription": "Electronics",
|
|
"containers": [ ... ]
|
|
}
|
|
```
|
|
|
|
**Step 5: Refresh Token (When Access Token Expires)**
|
|
```http
|
|
POST http://localhost:4000/auth/refresh
|
|
Content-Type: application/json
|
|
|
|
{
|
|
"refreshToken": "{{refreshToken}}"
|
|
}

## 🛡️ Security Measures
|
|
|
|
1. **Password Security**
|
|
- Argon2id algorithm (recommended by OWASP)
|
|
- 64MB memory cost
|
|
- 3 time iterations
|
|
- 4 parallelism
|
|
|
|
2. **JWT Security**
|
|
- Short-lived access tokens (15 min)
|
|
- Separate refresh tokens (7 days)
|
|
- Token type validation (access vs refresh)
|
|
- Signed with HS256
|
|
|
|
3. **Authorization**
|
|
- Organization-level data isolation
|
|
- Users can only access their own organization's data
|
|
- JWT guard enabled globally by default
|
|
|
|
4. **Error Handling**
|
|
- Generic "Invalid credentials" message (no user enumeration)
|
|
- Active user check on login
|
|
- Token expiration validation
|
|
