Course Outline
Orientation: Authentication & Security
Learn why security is a core system design pillar, and plan your secured API structure.
Passwords & Safe Storage (Hashing)
Understand the risk of plaintext storage and implement bcrypt hashing for user registration.
Credential Hygiene & Session Tokens (JWTs)
Implement credential environment loading and generate signed stateless JWT tokens.
Guarding the Gate (Auth Middleware)
Implement API auth dependencies to validate tokens and scope database queries to active users.
Role-Based Authorization
Differentiate user permissions by implementing role check boundaries (regular vs admin).
API Hardening (OWASP Basics)
Protect your web application against common security vulnerabilities like brute-force guessing and parameter tampering.
