• Sign up with Email verificiation
• Login
• User/Password Recovery via Email one time link
• Email address change with verification
• Password change
• User deletion

• March 2023: Added/Edited some files to run it with docker

Frontend is build with

• html5
• Javascript
• JQuery
• Bootstrap
• User deletion

Backend (Java) is build with

• Java 17
• Spring Boot
• Spring Data JPA
• Spring Mail
• Spring REST
• Freemarker for Emails

• JUnit5

Security

• provides https only connections (with redirect from http port)
• It uses a http only secure cookie with lax same site attribute and invalidates the cookie on logout.
• The cookie contains an JWT ID Token which is signed and verified on interaction
• Password is hashed with BCrypt

Get it running

Secrets

• config.properties (in test/main resources) pathToCert: path to X.509 certificate for public key (as pem)
• config.properties (in test/main resources) pathToPrivKey: path to corresponding private key pem file
• application.properties (in main resources) configure ssl keystore for https connection (server.ssl.key-store *)
• or set isMailingEnabled to false

Mail

• application.properties (in main resources) configure spring.mail.* for sending emails

Database

• Units tests are running with HSQL
• local start would in the current configuration also run with HSQL (that means on app server restart data is lost)
• To change update application.properties (in main resources) spring.datasource.*/ spring.jpa*

Other configs

• Have a closer look at config.properties (in test/main resources)
• E.g. switch off/on email sending by isMailingEnabled
• Switch off/on if user needs to click activation link to be active
• http port for https redirect (not nice but works)
• Id Token configs (TTL)
• base Urls for links in emails
• ...
