Generate a SHA hash from any text, instantly, right in your browser.
A hash is a fixed-length fingerprint of your input text — the same input always produces the same hash, but even a tiny change produces a completely different one. Hashes are commonly used to verify file integrity, check passwords without storing them directly, or confirm two pieces of text are identical without comparing them directly.
SHA-256 is the most widely used general-purpose choice today and is recommended for most needs. SHA-1 is older and considered weak for security purposes, though still used for basic checksums. SHA-512 produces a longer hash and offers a bit more collision resistance for specialized use cases.
No. This tool uses your browser's built-in Web Crypto API to generate the hash locally. Your input text is never transmitted anywhere.
