Distributed password manager implemented in java

High dependable system

Maven projects:

• keystore: Create and manage client keys

• client: Client interface to communicate with server

• server: Server with database

• lib: Shared library code between other projects

Our Password Manager is divided in 4 major projects: The Client, the Server, the KeyStore and the Lib. It is a RESTful system, so the Client and the Server communicate over HTTP, exchanging JSON Objects. For this process, we are using the Unirest Framework API in the Client-side to send requests, and the Spark Framework API on the Server-side to answer them. Both client and server depend on the Lib Project, that is a library that contains cryptographic methods and other shared code between the two sides of the system, and on the Keystore Project, an independent Key Manager, that generate and provides the client and the server a pair of Public/Private Keys.

• Install lib shared code

   cd lib
   mvn install
  

• Generate keystore to Tests

   cd keystore
   mvn compile exec:java
  

   ...
   Enter username: username
   Enter password: password
   ...
  

• Generate keystore to client

   cd keystore
   mvn compile exec:java
  

   ...
   Enter username: example
   Enter password: 123456789
   ...
  

• Run in parallel

  • start 4 server replicas

     cd server
     source start.sh 4
    
    

  • client

   	cd client
   	mvn compile exec:java -Dexec.args="localhost 8080 4"
   	```
  
   	```
   	# 1. Call init
   	# 2. Login with username and password from keystore
   	# 3. Register
   	# 4. Put and/or get passwords
   	```
  

• Run mvn tests on Lib

cd lib
mvn test
