  1. OWASP-ASVS v3.1-7.6 Verify that all random numbers, random file names, random GUIDs, and random strings are generated using the cryptographic module’s approved random number generator when these random values are intended to be not guessable by an attacker.

  2. OWASP-ASVS v3.1-7.15 Verify that random numbers are created with proper entropy even when the application is under heavy load, or that the application degrades gracefully in such circumstances.
