Classical Cryptography — EC-DSA — NIST P-256

EC-DSA based Q-Signer Classic

Elliptic Curve Digital Signature — NIST P-256 — Powered by Hytak TRNG — free for everyone

EC-DSA Q-Signer Classic uses Hytak Random Number (TRNG) for private key d and signing key k (both 256-bit). Public key Q = d×G on NIST P-256 curve. Signature = (r, s). Classical cryptography — combine with ML-DSA for Hybrid quantum-safe signing!

EC-DSA Core Equations — NIST P-256

Key Gen: Q = d × G
Sign: r = (k×G).x mod n
s = k⁻¹(hash + r×d) mod n
Verify: X = u1×G + u2×Q → X.x = r

d = private key (Hytak TRNG 256-bit)

Q = public key = d×G

G = P-256 base point

k = signing key (Hytak TRNG 256-bit)

r, s = signature output

n = P-256 curve order

How it works — EC-DSA NIST P-256

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

d = private key — Hytak TRNG generates 256-bit random number (secret, hidden)

Q = d × G — public key computed on NIST P-256 elliptic curve

hash = SHA256(m) — 256-bit message hash

k = signing key — Hytak TRNG generates new 256-bit random number (secret)

r = (k×G).x mod n — x-coordinate of point k×G

s = k⁻¹(hash + r×d) mod n — signature value

Verify: X = u1×G + u2×Q → X.x = r — signature verified! ✅
