About This Tool
The SHA-256 Generator computes the SHA-256 cryptographic hash of any text using your browser's built-in Web Crypto API — fast, accurate and secure.
Frequently Asked Questions
What is SHA-256 used for?
SHA-256 is widely used for data integrity verification, digital signatures, password storage (with salting), and blockchain technology.
Is SHA-256 more secure than MD5?
Yes, SHA-256 is part of the modern SHA-2 family and is considered cryptographically secure, unlike MD5 which is broken for security purposes.
How is this hash calculated?
This tool uses your browser's native Web Crypto API (crypto.subtle.digest), which implements the standard SHA-256 algorithm.
