Overview

CIFER SDK provides quantum-resistant encryption (ML-KEM-768 + AES-256-GCM) for blockchain apps. Secrets are on-chain key pairs: public key on IPFS, private key sharded across enclaves. Package: cifer-sdk (npm) Chains: Ethereum Mainnet (1), Sepolia (11155111), Ternoa (752025) Blackbox URL: https://cifer-blackbox.ternoa.dev:3010 For the full API reference, see reference.md.

Quick Setup

npm install cifer-sdk ethers dotenv package.json must have "type": "module" for ESM imports. import 'dotenv/config'; import { createCiferSdk, keyManagement, blackbox } from 'cifer-sdk'; import { Wallet, JsonRpcProvider } from 'ethers';

Step 1: Initialize SDK

const sdk = await createCiferSdk({ blackboxUrl: 'https://cifer-blackbox.ternoa.dev:3010', }); const chainId = 1; // Ethereum Mainnet (or 11155111 for Sepolia, 752025 for Ternoa) const controllerAddress = sdk.getControllerAddress(chainId); const rpcUrl = sdk.getRpcUrl(chainId); sdk.getSupportedChainIds() returns all available chains.

Step 2: Create Wallet Signer (Server-Side)

Step 3: Create a Secret

A secret costs a fee in native token. Check balance first. const fee = await keyManagement.getSecretCreationFee({ chainId, controllerAddress, readClient: sdk.readClient, }); const txIntent = keyManagement.buildCreateSecretTx({ chainId, controllerAddress, fee }); const tx = await wallet.sendTransaction({ to: txIntent.to, data: txIntent.data, value: txIntent.value, }); const receipt = await tx.wait(); const secretId = keyManagement.extractSecretIdFromReceipt(receipt.logs);

Step 4: Wait for Secret Sync

After creation, the enclave cluster generates keys (~30-120s on mainnet). let ready = false; while (!ready) { ready = await keyManagement.isSecretReady( { chainId, controllerAddress, readClient: sdk.readClient }, secretId, ); if (!ready) await new Promise(r => setTimeout(r, 5000)); } Or read the full state: const state = await keyManagement.getSecret( { chainId, controllerAddress, readClient: sdk.readClient }, secretId, ); // state.owner, state.delegate, state.isSyncing, state.publicKeyCid

Step 5: Encrypt Text

const encrypted = await blackbox.payload.encryptPayload({ chainId, secretId, plaintext: 'Your secret message', signer, readClient: sdk.readClient, blackboxUrl: sdk.blackboxUrl, }); // Returns: { cifer, encryptedMessage }

Step 6: Decrypt Text

Caller must be secret owner or delegate. const decrypted = await blackbox.payload.decryptPayload({ chainId, secretId, encryptedMessage: encrypted.encryptedMessage, cifer: encrypted.cifer, signer, readClient: sdk.readClient, blackboxUrl: sdk.blackboxUrl, }); // Returns: { decryptedMessage }

Step 7: Encrypt File

File operations are async jobs. Works with Blob in Node.js 18+. import { readFile, writeFile } from 'fs/promises'; const buffer = await readFile('myfile.pdf'); const blob = new Blob([buffer], { type: 'application/pdf' }); // Start encrypt job const job = await blackbox.files.encryptFile({ chainId, secretId, file: blob, signer, readClient: sdk.readClient, blackboxUrl: sdk.blackboxUrl, }); // Poll until done const status = await blackbox.jobs.pollUntilComplete(job.jobId, sdk.blackboxUrl, { intervalMs: 2000, maxAttempts: 120, onProgress: (j) => console.log(`${j.progress}%`), }); // Download encrypted .cifer file (no auth needed for encrypt jobs) const encBlob = await blackbox.jobs.download(job.jobId, { blackboxUrl: sdk.blackboxUrl }); await writeFile('myfile.pdf.cifer', Buffer.from(await encBlob.arrayBuffer()));

Step 8: Decrypt File

List Existing Secrets

const secrets = await keyManagement.getSecretsByWallet( { chainId, controllerAddress, readClient: sdk.readClient }, wallet.address, ); // secrets.owned: bigint[] — secrets you own // secrets.delegated: bigint[] — secrets delegated to you

Delegation

Set a delegate (can decrypt but not encrypt or modify): const txIntent = keyManagement.buildSetDelegateTx({ chainId, controllerAddress, secretId, newDelegate: '0xDelegateAddress', }); await wallet.sendTransaction({ to: txIntent.to, data: txIntent.data }); Remove delegation: const txIntent = keyManagement.buildRemoveDelegationTx({ chainId, controllerAddress, secretId, });

Important Notes

Minimum SDK version: Use cifer-sdk@0.3.1 or later. Earlier versions had incorrect function selectors. Payload size limit: Text encryption max ~16KB (encryptPayload). Use file encryption for larger data. Block freshness: The SDK auto-retries up to 3 times if the block number becomes stale. Secret sync time: ~30-60s on Ternoa, ~60-120s on Ethereum mainnet. Auth for file download: Encrypt job downloads need no auth. Decrypt job downloads require signer + readClient. Fee: Secret creation requires a fee in native token (e.g. ~0.0005 ETH on mainnet). Query getSecretCreationFee() first. Private keys: Never expose private keys in frontend code. Use server-side signer for Node.js.

Error Handling

import { isCiferError, isBlockStaleError } from 'cifer-sdk'; try { await blackbox.payload.encryptPayload({ ... }); } catch (error) { if (isBlockStaleError(error)) { // RPC returning stale blocks, SDK already retried 3x } else if (error instanceof SecretNotReadyError) { // Wait and retry } else if (isCiferError(error)) { console.error(error.code, error.message); } }

Complete Minimal Example

import 'dotenv/config'; import { createCiferSdk, keyManagement, blackbox } from 'cifer-sdk'; import { Wallet, JsonRpcProvider } from 'ethers'; const sdk = await createCiferSdk({ blackboxUrl: 'https://cifer-blackbox.ternoa.dev:3010' }); const chainId = 1; const controllerAddress = sdk.getControllerAddress(chainId); const provider = new JsonRpcProvider(sdk.getRpcUrl(chainId)); const wallet = new Wallet(process.env.PRIVATE_KEY, provider); const signer = { async getAddress() { return wallet.address; }, async signMessage(msg) { return wallet.signMessage(msg); }, }; // Create secret const fee = await keyManagement.getSecretCreationFee({ chainId, controllerAddress, readClient: sdk.readClient }); const txIntent = keyManagement.buildCreateSecretTx({ chainId, controllerAddress, fee }); const tx = await wallet.sendTransaction({ to: txIntent.to, data: txIntent.data, value: txIntent.value }); const receipt = await tx.wait(); const secretId = keyManagement.extractSecretIdFromReceipt(receipt.logs); // Wait for sync let ready = false; while (!ready) { ready = await keyManagement.isSecretReady({ chainId, controllerAddress, readClient: sdk.readClient }, secretId); if (!ready) await new Promise(r => setTimeout(r, 5000)); } // Encrypt & decrypt const enc = await blackbox.payload.encryptPayload({ chainId, secretId, plaintext: 'Hello CIFER!', signer, readClient: sdk.readClient, blackboxUrl: sdk.blackboxUrl, }); const dec = await blackbox.payload.decryptPayload({ chainId, secretId, encryptedMessage: enc.encryptedMessage, cifer: enc.cifer, signer, readClient: sdk.readClient, blackboxUrl: sdk.blackboxUrl, }); console.log(dec.decryptedMessage); // "Hello CIFER!"
