Security Utilities

The Utilities module provides foundational helpers for encoding, decoding, byte manipulation, and key derivation. These functions ensure consistency and performance across all cryptographic operations.

Encoding Utilities

Convert data between binary buffers and various string formats with zero-allocation efficiency.

Unified Utils Interface

The Utils object provides a consolidated entry point for the most commonly used operations.

import { Utils } from "xypriss-security";

// Quick Hash
const hex = Utils.hash("sensitive-data");

// Secure Random Bytes
const bytes = Utils.getRandomBytes(16);

// Fast string-to-string encryption (native bridge)
const encrypted = await Utils.encrypt("message", "passphrase");

Key Derivation (KDF)

Derive cryptographically strong keys from weak secrets using Argon2id, PBKDF2, or HKDF.

import { deriveKey } from "xypriss-security";

const key = await deriveKey("my-secret", {
  algorithm: "pbkdf2",
  iterations: 310000,
  keyLength: 32,
  salt: "unique-salt-string",
});

Byte Precision

getByteLength("you好"); // 8 bytes (好 = 3 bytes)
