🌟 Hashtegrity 🌟

Secure your data with ease! Hashtegrity is a powerful library for generating hashes and validating data integrity, ensuring your data remains untampered and secure.

🚀 Features

• Versatile Hashing: Supports multiple hashing algorithms like sha256, md5, and more.
• HMAC Generation: Easily generate HMACs for added security.
• Data Integrity Validation: Validate the integrity of your data with simple functions.
• File Integrity Validation: Validate the integrity of your file easily.
• File Integrity Monitoring: Monitor file changes and validate integrity in real-time.
• TypeScript Support: Fully typed for a seamless development experience.

📦 Installation

Install the package:

npm install hashtegrity

🛠️ Usage

Generate a Hash

import { generateHash } from "hashtegrity";

const hash = generateHash({ data: { key: "value" }, algorithm: "sha256" });

Generate an HMAC

import { generateHash } from "hashtegrity";

const hmac = generateHash({
  data: "message",
  key: "secret-key",
  algorithm: "sha256",
});

Generate a File Hash

import { generateFileHash } from "hashtegrity";

const hash = await generateFileHash({
  filePath: "path/to/your/file.txt",
  algorithm: "sha256",
});

Generate Directory Hash

import { generateDirectoryHash } from 'hashtegrity';

const hash = await generateDirectoryHash({
  directoryPath: "path/to/directory",
});

Validate Data Integrity

import { validateIntegrity } from 'hashtegrity';

const isValid = await validateIntegrity({
  type: "data",
  data: "your-data-of-any-type",
  expectedHash: "4d4f638fd1c15eb71e1c7b46556c6d76cf6cc0cf1961d9e39a5fdc988a22cfe2",
  algorithm: "sha256",
});

Validate File Integrity

import { validateIntegrity } from 'hashtegrity';

const isValid = await validateIntegrity({
  type: "file",
  filePath: "path/to/your/file.txt",
  expectedHash: "4d4f638fd1c15eb71e1c7b46556c6d76cf6cc0cf1961d9e39a5fdc988a22cfe2",
  algorithm: "sha256",
});

Validate Directory Integrity

import { validateIntegrity } from 'hashtegrity';

const isValid = await validateIntegrity({
  type: "directory",
  filePath: "path/to/your/directory",
  expectedHash: "4d4f638fd1c15eb71e1c7b46556c6d76cf6cc0cf1961d9e39a5fdc988a22cfe2",
  algorithm: "sha256",
});

Monitor File Integrity

import { monitorIntegrity } from 'hashtegrity';

const options = {
  type: "file",
  filePath: "path/to/your/file.txt",
  algorithm: "sha256",
  key: "your-secret-key",
  metadata: { custom: "data" },
  expectedHash:
    "4d4f638fd1c15eb71e1c7b46556c6d76cf6cc0cf1961d9e39a5fdc988a22cfe2",
  onIntegrityCheckFailed: (error) => {
    console.error("Integrity check failed:", error);
  },
  onError: (error) => {
    console.error("Error:", error);
  },
};

await monitorIntegrity(options);
console.log("Monitoring started");

Monitor Directory Integrity

import { monitorIntegrity } from 'hashtegrity';

const options = {
  type: "directory",
  filePath: "path/to/your/directory",
  algorithm: "sha256",
  key: "your-secret-key",
  metadata: { custom: "data" },
  expectedHash:
    "4d4f638fd1c15eb71e1c7b46556c6d76cf6cc0cf1961d9e39a5fdc988a22cfe2",
  onIntegrityCheckFailed: (error) => {
    console.error("Integrity check failed:", error);
  },
  onError: (error) => {
    console.error("Error:", error);
  },
};

await monitorIntegrity(options);
console.log("Monitoring started");
