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
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');Related JSON Tools
