Hybrid encryption (ECDH P-256 + AES-256-GCM) with Express middleware for automatic request/response encryption. Also supports RSA-2048 OAEP.

Zero-dependency cryptographic primitives for Node.js — hash / hmac / KDFs (PBKDF2, HKDF, scrypt), AES-GCM / ChaCha20-Poly1305 / RSA-OAEP ciphers, RS/PS/ES/EdDSA signatures, signed cookies, sealed timed tokens, CSPRNG (UUID v4/5/7, ULID, base58, crockford)

## Algorithms 1. AES (AES-GCM) 2. ECDH 3. PBKDF2 4. RSA (RSA-OAEP)

Encrypts a payload using AES-256 and RSA-OAEP (Hybrid Encryption)

Secure PIN / password keypad for Expo (New Architecture). Natively rendered shuffled keys, the entered value never enters the JS runtime, mlock'd C++ buffer, OpenSSL RSA-OAEP ciphertext only. Screen-capture blocking and device integrity are the host app's

Production-ready hybrid encryption middleware for Express.js with RSA-OAEP + AES-256-GCM

Zero-dependency RFC 7516/7515 compact JWE (RSA-OAEP-256 + A256GCM) and JWS (RS256) implementation for Node.js

Node.js hybrid encryption (RSA-OAEP + AES-256-GCM) for backend services

Universal AES-256-CBC + RSA-OAEP-4096 encryption for Node.js, Express, React, Vite, and Next.js.

Browser hybrid encryption (RSA-OAEP + AES-256-GCM) using the WebCrypto API

**CryptoToolkit** is a comprehensive encryption and data security library designed for web applications. It provides easy-to-use functions for encrypting and decrypting data, as well as managing encryption keys. With support for **AES-GCM** and **RSA-OAEP

Axios request payload encryption with optional Vue plugin support using RSA-OAEP and AES-GCM.

Node crypto helpers implemented for real: AES-256-GCM encrypt/decrypt with a portable payload format, scrypt key derivation, timing-safe HMAC-SHA256 sign/verify, and RSA-OAEP encrypt/decrypt with a key-pair generator.

Web Cryptography API shim for legacy browsers

Cryptographic escrow of JSON data and files into a filesystem vault. Data and file keys are encrypted to a public escrow key (RSA-OAEP or ECDH-ES) as JWE; files are streamed AES-256-GCM. Each escrow is a self-contained, atomically placed directory.

Minimal implementation of older cryptography algorithms: RSA, DSA, DH, ElGamal

JWE encryption for Express.js and Node.js APIs — RSA-OAEP-256 + AES-256-GCM.
