# encryption-utils

Install: npm install @ferrow/encryption-utils
> 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.

Small, real implementations of the crypto primitives you actually reach for, built directly on Node's `crypto` module. No third-party dependency, no home-grown cipher — just a sane API around what Node already ships.

## API
- `encrypt`
- `decrypt`
- `decryptToString`
- `DeriveKeyOptions`
- `deriveKey`
- `generateSalt`
- `hmacSign`

- `RsaKeyPair`
- `generateKeyPair`
- `rsaEncrypt`
- `rsaDecrypt`

## Install
Each library is a standalone GitHub repo under github.com/FerrowAI.
