Below are detailed examples to demonstrate the capabilities and usage of this library using ESM syntax and TypeScript. +### 🔤 String Hashing -### Hashing Strings -#### SHA-256 ```typescript import { sha256FromString, sha256FromStringSync } from '@push.rocks/smarthash'; -// Asynchronously hash a string -const asyncHash = async () => { - const hash = await sha256FromString('Hello, world!'); - console.log(hash); // Output the hashed string -}; -asyncHash(); +// Async (works everywhere) +const hash = await sha256FromString('Hello, world!'); +console.log(hash); // 📄 64-character hex string -// Synchronously hash a string -const syncHash = sha256FromStringSync('Hello, world!'); -console.log(syncHash); // Output the hashed string +// Sync (Node.js only) +const hashSync = sha256FromStringSync('Hello, world!'); +console.log(hashSync); // ⚡ Instant result ``` -#### MD5 +### 🗂️ File & Stream Hashing (Node.js Only) + +```typescript +import { sha256FromFile, sha256FromStream } from '@push.rocks/smarthash'; +import fs from 'fs'; + +// Hash files directly +const fileHash = await sha256FromFile('./myfile.txt'); +console.log(fileHash); // 📁 File's SHA256 hash + +// Hash streams (perfect for large files) +const stream = fs.createReadStream('./largefile.zip'); +const streamHash = await sha256FromStream(stream); +console.log(streamHash); // 🌊 Stream's SHA256 hash +``` + +### 🧱 Buffer Hashing + +```typescript +import { sha256FromBuffer } from '@push.rocks/smarthash'; + +// Works with both Buffer (Node.js) and Uint8Array (Browser) +const encoder = new TextEncoder(); +const buffer = encoder.encode('Hello, world!'); +const bufferHash = await sha256FromBuffer(buffer); +console.log(bufferHash); // 🔢 Buffer's SHA256 hash +``` + +### 🎯 Object Hashing + +```typescript +import { sha256FromObject } from '@push.rocks/smarthash'; + +// Consistent hashing for JavaScript objects +const myObject = { + userId: 12345, + role: 'admin', + timestamp: Date.now() +}; + +const objectHash = await sha256FromObject(myObject); +console.log(objectHash); // 🎯 Deterministic object hash +``` + +> **🔥 Pro Tip**: Object property order doesn't matter! `{a: 1, b: 2}` and `{b: 2, a: 1}` produce the same hash. + +### 🛡️ MD5 Hashing (Node.js Only) + ```typescript import { md5FromString } from '@push.rocks/smarthash'; -// Asynchronously hash a string with MD5 -const md5Hash = async () => { - const hash = await md5FromString('Hello, world!'); - console.log(hash); // Output the MD5 hash -}; -md5Hash(); +// Legacy MD5 support (use SHA256 for new projects!) +const md5Hash = await md5FromString('Hello, world!'); +console.log(md5Hash); // 🔐 32-character MD5 hash ``` -### Hashing Files -To hash a file, you can use the `sha256FromFile` function. It reads the file specified by the path and calculates the SHA-256 hash. -```typescript -import { sha256FromFile } from '@push.rocks/smarthash'; +## 🌍 Environment Compatibility -// Asynchronously hash a file -const hashFile = async () => { - const fileHash = await sha256FromFile('./path/to/your/file.txt'); - console.log(fileHash); // Output the file's hash -}; -hashFile(); -``` +| Function | Node.js | Browser | Notes | +|----------|---------|---------|-------| +| `sha256FromString` | ✅ | ✅ | Universal support | +| `sha256FromStringSync` | ✅ | ❌ | Sync not possible in browsers | +| `sha256FromBuffer` | ✅ | ✅ | Handles Buffer/Uint8Array | +| `sha256FromFile` | ✅ | ❌ | File system access required | +| `sha256FromStream` | ✅ | ❌ | Node.js streams only | +| `sha256FromObject` | ✅ | ✅ | Uses JSON serialization | +| `md5FromString` | ✅ | ❌ | Not supported by Web Crypto API | -### Hashing Streams -`@push.rocks/smarthash` also allows for hashing of streams, which is particularly useful for large files or data streams. -```typescript -import { sha256FromStream } from '@push.rocks/smarthash'; -import fs from 'fs'; +## 🔧 Advanced Usage -// Create a read stream from a file -const readStream = fs.createReadStream('./path/to/your/largeFile.txt'); +### Error Handling -// Asynchronously hash the stream -const hashStream = async () => { - const streamHash = await sha256FromStream(readStream); - console.log(streamHash); // Output the hash of the stream's content -}; -hashStream(); -``` - -### Advanced Usage -#### Hashing Objects -For hashing JavaScript objects, you can serialize them and hash the resulting string. This is useful for creating hashes from complex data structures. -```typescript -import { sha265FromObject } from '@push.rocks/smarthash'; - -// Hash a JavaScript object -const hashObject = async () => { - const object = { hello: 'world', number: 42 }; - const objectHash = await sha265FromObject(object); - console.log(objectHash); // Output the hash of the object -}; -hashObject(); -``` - -#### Error Handling -All asynchronous functions return promises, so you can use `.catch()` for error handling or try-catch blocks within async functions. ```typescript import { sha256FromString } from '@push.rocks/smarthash'; -// Using .catch() for promises -sha256FromString('test') - .then(hash => console.log(hash)) - .catch(error => console.error(error)); - -// Using try-catch with async functions -const getHash = async () => { - try { - const hash = await sha256FromString('test'); - console.log(hash); - } catch (error) { - console.error(error); - } -}; -getHash(); +try { + const hash = await sha256FromString('sensitive data'); + console.log(`✅ Hash computed: ${hash}`); +} catch (error) { + console.error('❌ Hashing failed:', error); +} ``` -### Best Practices -- Utilize asynchronous functions for hashing large files or streams to avoid blocking the main thread. -- For hashing sensitive information, ensure to follow security best practices, including using up-to-date algorithms and managing secrets properly. +### Browser-Specific Features -By leveraging `@push.rocks/smarthash`, developers can easily integrate hashing functionalities into their Node.js applications, benefiting from its simplified API and TypeScript support for better development experience. +In browsers, SmartHash automatically: +- 🔒 Uses Web Crypto API when available (HTTPS contexts) +- 🔄 Falls back to pure JavaScript implementation in non-HTTPS environments +- ⚠️ Warns when trying to use Node.js-only functions + +### Import Strategies + +```typescript +// Main entry point (Node.js optimized) +import { sha256FromString } from '@push.rocks/smarthash'; + +// Browser-specific entry point (smaller bundle) +import { sha256FromString } from '@push.rocks/smarthash/web'; +``` + +## 🛠️ Development + +```bash +# Run tests (both Node.js and browser) +pnpm test + +# Build the project +pnpm build + +# Generate documentation +pnpm buildDocs +``` + +## 🔐 Security Notes + +- ✅ **SHA256**: Cryptographically secure, recommended for all use cases +- ⚠️ **MD5**: Legacy support only, not recommended for security-critical applications +- 🌍 **Cross-Environment**: Produces identical hashes across Node.js and browsers +- 🔒 **Web Crypto**: Uses native browser APIs when available for maximum performance + +## 🤝 Contributing + +We welcome contributions!
