Calculate SHA256 hash from text.
Enter the text you want to hash.
Our free SHA256 hash generator creates secure SHA-256 hashes instantly. SHA-256 is an industry-standard cryptographic hash function used in blockchain, SSL certificates, password security, and data integrity verification. All processing happens locally in your browser for maximum security.
import hashlib
text = "Hello World"
hash = hashlib.sha256(text.encode()).hexdigest()
print(hash)const crypto = require('crypto');
const text = 'Hello World';
const hash = crypto.createHash('sha256').update(text).digest('hex');
console.log(hash);import java.security.MessageDigest;
MessageDigest md = MessageDigest.getInstance("SHA-256");
byte[] hash = md.digest("Hello World".getBytes());SHA-256 is part of the SHA-2 family of cryptographic hash functions designed by the NSA. It generates a unique 256-bit (32-byte) signature for a text or file, always producing a 64-character hexadecimal string. SHA-256 is one of the most secure and widely-used hashing algorithms.
SHA-256 is one of the most secure hashing algorithms available and is used in blockchain technologies (Bitcoin), SSL/TLS certificates, password hashing, digital signatures, and data integrity verification. It's resistant to collision attacks and provides strong security guarantees.
A SHA-256 hash is always exactly 64 hexadecimal characters (256 bits) long, regardless of the input size. Whether you hash a single character or a large file, the output will always be 64 characters.
