Cryptography operators

5 operators in the cryptography category of the live registry. Compose them in a contract or call POST /api/zeq/compute — KO42 is always on, plus up to three more per call.

How it computes: dedicated closed-form solver solveCRYPTO — real equations over CODATA-2018 constants; where an operator needs a series/matrix/field a scalar cannot express, it refuses honestly. See the solvers.

OperatorDescriptionEquation
CRYPTO_DHDiffie-Hellman key exchange enabling two parties to establish a shared secret over an insecure channel.K = g^{ab} \mod p = (g^a)^b \mod p = (g^b)^a \mod p
CRYPTO_ECCElliptic curve cryptography point addition on the Weierstrass curve over a finite field.y^2 = x^3 + ax + b \pmod{p}, \quad P + Q = R
CRYPTO_ENTROPYShannon entropy measuring the average information content and unpredictability of a cryptographic key or message.H(X) = -\sum_{i=1}^{n} p(x_i) \log_2 p(x_i)
CRYPTO_HASH_COLLISIONBirthday bound probability of hash collision in a hash function with n-bit output after k random inputs.P(\text{collision}) \approx 1 - e^{-k^2 / (2 \cdot 2^n)}
CRYPTO_RSARSA encryption/decryption using modular exponentiation with public key (e, n) and private key (d, n).c = m^e \mod n, \quad m = c^d \mod n

Compute one — a real call​

curl -sS -X POST https://zeqsdk.com/api/zeq/compute \
  -H "Authorization: Bearer $ZEQ_KEY" \
  -H "Content-Type: application/json" \
  -d '{"operators":["CRYPTO_HASH_COLLISION"],"inputs":{"k":4294967296,"n":64}}'

Returns 0.3935 probability — with unit, uncertainty, the generated master equation, and a signed envelope you can verify.
