What distinguishes symmetric encryption from asymmetric encryption?

  • Different keys for encryption and decryption
  • Only used for secure web communication
  • Same key for both encryption and decryption
  • Uses a key pair for encryption
Symmetric encryption uses the same key for both encryption and decryption, while asymmetric encryption uses different keys for these operations.

What is a primary challenge when implementing Microservices Architecture?

  • Monolithic Deployment
  • Service Coordination
  • Single Database Structure
  • Tight Coupling
