Crytography Services Restful API

A restful API that provides cryptographic services such as: symmetric encryption and decryption, asymmetric encryption and decryption, hashing data, digitally signing data, digital signature verification, key storing and retrieving

Link: http://3.15.178.19:5000/

The purpose of the project is to learn and practice concepts:

• Building a RESTful API.
• Strengthening knowledge on crypto services
• MVC Architectural Pattern.

Following technologies and framework were used:

• Flask framework, flask blueprints pattern
• Flask-JWT- Extended for user authentication
• PyCrypto Library for encryption (AES,RSA), hashing(SHA256) and digital signatures(PKCS1)
• Werkzeug Web Server Gateway Interface
• SQLite relational database used as backend database
• HTTP (GET, POST, PUT, PATCH, DELETE, status codes)
• Postman for testing endpoints

API Endpoints:

Sample Endpoints from Postman:

• Generate symmetric key:
• Generate asymmetric key:
• Symmetric Encryption:
• Symmetric Decryption:
• Sign and verify signature:
• User Register and Login: (Note: Succesful login will generate a token)
• Store and retreive keys (Note: Token is required for authorization)

To activate virtual env on AWS for update:

source venv/bin/activate

Restart API:

pkill gunicorn gunicorn --bind 0.0.0.0:5000 main:app
