Secure Your Communications with Technical Precision.
The all-in-one cryptographic suite for developers and security professionals. Generate RSA keypairs, encrypt text and files with hybrid RSA + AES-GCM up to 50MB, and digitally sign messages with confidence.
// Initializing RSA-4096 Generator
const { publicKey, privateKey } = generateKeyPairSync ('rsa', {
modulusLength: 4096,
publicKeyEncoding: { type: 'spki', format: 'pem' },
privateKeyEncoding: { type: 'pkcs8', format: 'pem' }
});
Security First
