"""
This script generates a cryptographically secure, complex random number by combining
system entropy sources (time, platform info, secure random bytes) and hashing them.

Use cases for the generated random number include:
- Creating unique primary keys or identifiers in databases
- Generating secure tokens or session IDs
- Seeding cryptographic or security-related algorithms
- Producing non-predictable filenames or cache keys
- Any application requiring high-entropy, unpredictable numeric values
