॥ The Anatomy of the Offering ॥

Block Structure & Padding

Observe how the Scattered Salt Injection (SSI) places salt bytes independently, followed by Merkle-Damgård padding and 64-bit length enclosure.

Final 512-bit State

The 8 × 64-bit internal registers after absorbing the padded blocks and executing the final permutations. Initialized using fractional components of prime roots.

॥ The Eight Paths ॥

Architecture (v4 Parity)

SSI

Scattered Salt

Salt bytes are dynamically placed at independent positions via a hash-derived scatter algorithm, preventing clustering.

pos[i] = f(data_hash, salt_hash, i)

TPL

Token Pipeline

Buffer splits into variable-length tokens. Each undergoes a Fisher-Yates byte shuffle and rolling XOR before absorption.

shuffle(token, fisher_yates(th))

SHM

SipHash Mixer

A robust 2-round SipRound-inspired 64-bit mixer guarantees excellent avalanche properties for internal metadata hashing.

v1=rotl(v1,13)^v0; v3=rotl(v3,16)^v2;

DOM

Domain Separation

Cryptographic separation guarantees inputs hashed as strings vs files start with mathematically distinct IVs.

s[5] ^= frac(pi) * 2^64

WHT

State Whitening

All 8 words are XOR'd with specific constants and salt tweaks, then fully permuted to erase IV-recovery vectors entirely.

s[i] ^= WK[i] ^ rotl(salt_h, ...)

ASR

Asymmetric Rotations

Period-64 rotation schedule ensures all offsets are strictly within [1, 63]. No undefined behavior (UB), maximizing diffusion.

v = rotl64(v, ROUND_ROT[idx])

॥ The Dance of Nataraja ॥

Permutation Stepper

Step through the mathematical choreography of the hash. Watch the state registers evolve block by block in true 3D space.

Phase: Idle | Op: —

Press Initialize State to load the current input into the stepper.

॥ The Third Eye's Glare ॥

Avalanche Effect

A single altered bit creates cosmic chaos. Modify the inputs below and observe the Strict Avalanche Criterion (SAC) targeting ~50% bit flip.

* Rudra-512 is intentionally compute-heavy. The Scattered Salt Injection, Tokenization Pipeline, and Full-Round Whitening serve as deliberate deterrents to ASIC/GPU brute-forcing, acting akin to key-stretching functions while remaining a general-purpose hash.
