# The jitterentropy_rng kernel module provides a reliable and hardware-independent source of cryptographic entropy by measuring
# minute variations in CPU execution timing (jitter). These microsecond-level differences are unpredictable and rooted in
# physical randomness, making them suitable for high-quality entropy generation. Unlike other RNG methods that rely on hardware
