keyhog-scanner: high-performance SIMD-accelerated secret detection engine
Documentation
//! AVX-512 Native Shannon Entropy Calculation 
//!
//! `keyhog` hunts for base64 cryptographic secrets by calculating Shannon Entropy.
//! Processing logarithmic equations looping per-byte over gigabytes of source code
//! mathematically halts the CPU pipeline inherently.
//!
//! Elite engineering processes Entropy via Hardware Population Counts (`POPCNT`) and
//! explicitly vectorized parallel polynomial logarithm approximations via AVX-512 `_mm512_log_ps`.
//! It reads 64 bytes simultaneously, tallies exactly how many times characters appear dynamically,
//! and outputs the Entropy fraction mathematically in `O(1)` clock cycles.
