◆ INTEGRITY STREAM
Tamper-evident, in real time
Each seal, handshake, and key rotation is hashed and logged the instant it happens.
// ZERO-TRUST DATA INTEGRITY
Integrity you can prove, not just promise.
Cyverra wraps every payload, key, and request in tamper-evident cryptographic verification. One SDK. Six-millisecond overhead. Built for developers who ship alone.
- 0ms p99 verify overhead
- 0 native SDKs
- 256-bit sealed payloads
- 0 trust assumed

01 — INTEGRITY
A live readout of every byte under watch.
Cyverra is an instrument panel for your data. Every operation is sealed, streamed, and provable — no dashboards to babysit, no trust to assume.
◆ API — /v1/verify
One endpoint. A binary answer.
◆ ZERO-TRUST
Four layers, independently verified
L4 Identityattested
L3 Transportpinned
L2 Payloadsealed
L1 Attestationsigned
◆ LATENCY
0ms
p99 verification overhead, measured edge-to-edge.
◆ TOPOLOGY — ZERO STANDING TRUST
Every node verifies every other node
◆ STATUS

02 — PIPELINE
Three lines between you and provable integrity.
No agents, no sidecars, no infrastructure to run. Cyverra is a library and an endpoint — that is the whole footprint.
01
Install the SDK
One dependency, eleven languages. No build-step changes, no native bindings to compile.
npm i @cyverra/sdk
02
Seal your data
Wrap any payload, token, or key. Cyverra returns a sealed object that carries its own proof.
const s = await seal(data)
03
Verify everywhere
Any service, edge, or client checks integrity in microseconds. Tampering throws — loudly.
verify(s) → intact
03 — INTEGRATE
Engineered to disappear into your stack.
Cyverra reads like the standard library you wish you had. Drop it in, ship, and forget it’s there — until something tries to tamper.
-
Deterministic & offline-verifiableSealed objects prove themselves without a network call.
-
Key rotation on a 24-hour clockAutomatic, zero-downtime, fully auditable.
-
Tamper events are loud, not silentA failed check throws a typed error — never a quiet false.

# install
npm install @cyverra/sdk
import { seal, verify } from '@cyverra/sdk';
const sealed = await seal(payload, {
key: process.env.CYVERRA_KEY,
});
const ok = await verify(sealed); // → true | TamperError
# install
pip install cyverra
from cyverra import seal, verify
sealed = seal(payload, key=os.environ["CYVERRA_KEY"])
ok = verify(sealed) # → True | TamperError
// add the crate
cargo add cyverra
use cyverra::{seal, verify};
let sealed = seal(&payload, &key)?;
let ok = verify(&sealed)?; // → true | TamperError
curl https://api.cyverra.dev/v1/seal \
-H "authorization: Bearer $CYVERRA_KEY" \
-d '{"payload":"…"}'
# → { "sealed": "cyv_1.aF9…", "alg": "ed25519" }

Ship secure by default.
Drop in one SDK and every byte you handle becomes provable. Start free — no card, no sales call.
