Encryption Algorithms

Homomorphic Encryption Schemes

Different schemes support different operations. Select an algorithm to see its capabilities.

BFV (Brakerski-Fan-Vercauteren)

Supports addition and multiplication on integers. Ideal for exact arithmetic computations.

API Integration

WIA-SEC-012 API Integration

Generate code snippets for integrating homomorphic encryption into your applications.

Programming Language

Use Case

Code Example:

// TypeScript Example - Basic Encryption/Decryption
import { WIAHomomorphic } from '@wia/sec-012';

// Initialize the client
const client = new WIAHomomorphic({
  scheme: 'BFV',
  polyModulusDegree: 4096,
  plainModulus: 1024
});

// Generate keys
const { publicKey, secretKey } = await client.generateKeys();

// Encrypt data
const plaintext = 42;
const ciphertext = await client.encrypt(plaintext, publicKey);

// Perform computation on encrypted data
const doubled = await client.multiply(ciphertext, 2);

// Decrypt result
const result = await client.decrypt(doubled, secretKey);
console.log('Result:', result); // 84
                    

Installation:

npm install @wia/sec-012
# or
pip install wia-sec-012
# or
cargo add wia-sec-012
