Authentication Component

The Scava Authentication service:

• Provides a centralized mechanisms to securize Scava's components and manage authentication for all services of the platform.
• Provides user management services, including user registration process, user profile editing and roles based authorization management.

Authentication API

The Authentication server is a component of The Scava platform which manages the authentication for all services accessible behind the API Gateway.

Authenticate User	POST	/api/authentication
Login as a registered user.

### JSON Web Tokens (JWT) JSON Web Token (JWT) is an open industry standard (RFC 7519) that defines a compact and self-contained way for securely transmitting information between parties as a JSON object. It consists of three parts separated by dots (.), which are: * Header * Payload * Signature This solution uses a secure token that holds the information that we want to transmit and other information about our token, basically the user’s **login name** and **authorities**. (Find more about JWT: https://jwt.io/). ### JWT Authentication Implementation * Users have to login to the authentication service API using their credentials username and password.

curl -i -X POST -H "Content-Type:application/json" http://localhost:8086/api/authentication -d '{"username":"admin", "password": "admin"}'

* Once the user is authenticated, he will get a JWT token in the HTTP Response Authorization Header. * The generated token will be used by injecting it inside the HTTP Request Authorization Header to get access to the different Scava's components behind the API Gateway.

curl -i -X GET -H "Content-Type:application/json" -H "Authorization:Bearer eyJhbGciOiJIUzI1NiJ9.eyJzdWIiOiJhZG1pbiIsImF1dGhvcml0aWVzIjpbIlJPTEVfQURNSU4iLCJST0xFX1BST0pFQ1RfTUFOQUdFUiIsIlJPTEVfVVNFUiJdLCJpYXQiOjE1MzE4OTk3NDMsImV4cCI6MTUzMTk4NjE0M30.l-iCJcnae-1mlhMb3_y09HM4HZYFaHxe_JctWi2FRUY" http://localhost:8086/api/users
