About

SHA-256 (Secure Hash Algorithm 256-bit) generates a 256-bit (32-byte) hash value, typically rendered as a 64-character hexadecimal number. SHA-256 is cryptographically secure and widely used for generating unique identifiers, checksums, and cryptographic signatures. It's part of the SHA-2 family and is the recommended hash function for most security-critical applications. SHA-256 provides strong collision resistance and is used in Bitcoin, SSL/TLS certificates, and many security protocols.

Use Cases

  • •Cryptographically secure unique identifiers
  • •Content-addressable storage
  • •Digital signatures and certificates
  • •Blockchain and cryptocurrency applications
  • •Password hashing (with salt)
  • •Data integrity verification
  • •API keys and tokens

How to Generate

Code Example

import CryptoJS from 'crypto-js';

// Hash input text
const hash = CryptoJS.SHA256('input text').toString();

// Or hash random bytes
const randomBytes = CryptoJS.lib.WordArray.random(16);
const randomHash = CryptoJS.SHA256(randomBytes).toString();
