Cryptographic Hash — SHA1024 & SHA1536 — Stronger than SHAKE256

Hytak Hash

SHA1024 and SHA1536 — free for everyone

SHA1024 = 4 chained SHA256 = 1024 bits | SHA1536 = 6 chained SHA256 = 1536 bits. Both are simpler and stronger, and can replace SHAKE256 (1600-bit buffer, Keccak algorithm). Applications: secure hashing, digital signatures, random number generation.

Hytak Hash — Core Equations

SHA1024:
  h1 = SHA256(m)
  h2 = SHA256(h1)
  h3 = SHA256(h2)
  h4 = SHA256(h3)
  SHA1024 = h1 ‖ h2 ‖ h3 ‖ h4 ← 1024 bits

SHA1536:
  h1~h4 = same as above
  h5 = SHA256(h4)
  h6 = SHA256(h5)
  SHA1536 = h1 ‖ h2 ‖ h3 ‖ h4 ‖ h5 ‖ h6 ← 1536 bits

m = input message (image or name)

‖ = concatenation

SHA1024 = 256 hex chars

SHA1536 = 384 hex chars

How it works

Upload image or type your name — used as input message m

SHA1024: h1=SHA256(m), h2=SHA256(h1), h3=SHA256(h2), h4=SHA256(h3) → concatenate → 1024 bits ✅

SHA1536: continue h5=SHA256(h4), h6=SHA256(h5) → concatenate all 6 → 1536 bits ✅

Both hashes displayed — hex format, each round shown separately ✅
