Description

SHA-256 is part of the SHA-2 family and produces a 256-bit hash value. It's currently the industry standard for cryptographic hashing, widely used in blockchain, digital certificates, and secure communications.

Use Cases & Applications

Password Storage
Digital Signatures
Blockchain Technology
SSL/TLS Certificates

Implementation Examples

// Node.js SHA-256 Implementation (Recommended)
const crypto = require('crypto');

function calculateSHA256(text) {
    const hash = crypto.createHash('sha256');
    hash.update(text, 'utf8');
    return hash.digest('hex');
}

// Usage example
const text = "Hello World";
const result = calculateSHA256(text);
console.log(`SHA-256: ${result}`);

// Alternative: One-liner for simple cases
const quickHash = crypto.createHash('sha256')
    .update(text, 'utf8')
    .digest('hex');
