Why does Flask use the SECRET_KEY to sign session cookies instead of encrypting them?
ASigning ensures data integrity without needing to decrypt on server
BEncryption is slower and not supported by Flask
CSigning hides the session data from users
DEncryption requires storing keys on client side
Step-by-Step Solution
Solution:

  1. Step 1: Understand signing vs encryption

    Signing verifies data was not changed but does not hide data content.

  2. Step 2: Reason why Flask signs sessions

    Flask signs session cookies so it can detect tampering without decrypting, improving performance.

  3. Final Answer:

    Signing ensures data integrity without needing to decrypt on server -> Option A

  4. Quick Check:

    Flask signs cookies to verify integrity, not encrypt [OK]
Quick Trick: Signing checks data integrity; encryption hides data [OK]
Common Mistakes:
MISTAKES
  • Thinking signing hides data
  • Believing encryption is unsupported
  • Assuming encryption keys stored client-side
