Tequel (TQL-11)

Crates.io Version

Tequel is a high-performance cryptographic integrity engine and hash function implemented in pure Rust, optimized for AVX2-capable x86_64 architectures.

Technical Architecture (TQL-11)

The TQL-11 core utilizes an ARX (Addition-Rotation-XOR) primitive designed for high-density bit diffusion and hardware-level efficiency.

Register Pinning: Maps internal states directly to YMM registers to minimize stack spilling and maximize execution unit utilization.
Loop Unrolling: 2x unrolling (128 bytes per iteration) to reduce branch overhead and improve Instruction-Level Parallelism (ILP).
SIMD Implementation: Parallel YMM processing with asymmetric bit-twisting for distinct entropy paths.
Zero-Allocation Pipeline: Uses static lookup tables for hexadecimal serialization and memory-mapped data processing.

Performance Benchmarks

Benchmarks conducted using Criterion on x86_64 hardware. Environment: 8-core / 16-thread | target-cpu=native | AVX2.

Throughput Scaling

Payload Size	Throughput (v1.1.0)	Note
1024 bytes	12.44 MiB/s	Setup overhead dominant
1 MB	7.89 GiB/s	Single-core saturation
100 MB (Parallel)	25.13 GiB/s	Multi-threaded (Rayon)

Comparative Analysis (Single-Core 1MB)

Algorithm	Throughput	Implementation
SHA-384	~604 MiB/s	Standard ARX
Tequel (TQL-11)	~7.89 GiB/s	Native AVX2

Statistical Validation

Strict Avalanche Criterion (SAC): 50.14%
Shannon Entropy: 7.999991 bits/byte
Heap Usage: Zero dynamic allocations during hashing process
Determinism: Guaranteed across x86_64-avx2 platforms

Usage

Rust

Add to Cargo.toml:

tequel-rs = "1.2.0"

use tequel::hash::TequelHash;

fn main() {
    let mut teq = TequelHash::new();
    let data = b"example_data";
    let hash = teq.tqlhash(data);
    println!("Hash: {}", hash);
}

C Interoperability

#include "tequel.h"
#include <stdio.h>

int main() {
    uint8_t input[] = "data";
    uint8_t hash[48];
    tequel_hash_raw(input, sizeof(input), hash);
    return 0;
}

Benchmarking

To reproduce results on your local hardware:

$env:RUSTFLAGS="-C target-cpu=native"; cargo bench

Etymology

"Tequel" refers to the concept of "being weighed" (Daniel 5:27), representing the verification of data integrity.
