A hash is a fixed-length fingerprint of data. Feed in any text and you get a unique string back, change one character and the hash changes completely. You can generate SHA-256, SHA-1 and SHA-512 hashes of any text in one click.
What hashes are for
- Integrity checks, verify a file or message wasn't altered.
- Checksums, confirm a download matches the original.
- Fingerprints, compare data without storing it directly.
SHA-256 vs SHA-1 vs SHA-512
SHA-256 is the modern standard, secure and widely used. SHA-1 is older and considered weak for security, but still appears in legacy systems. SHA-512 produces a longer hash for extra collision resistance.
How to generate a hash (step by step)
- Open the Hash Generator and type your text.
- Pick an algorithm (SHA-256 is a safe default).
- Generate, the hash is created and copied for you.

How do I generate a SHA-256 hash?
Type your text, keep SHA-256 selected and click Generate. The hexadecimal hash appears and is copied to your clipboard.
Which hash algorithms are supported?
SHA-256, SHA-1 and SHA-512. SHA-256 is the most common choice for checksums today.
Is the hashing done securely?
Yes. It uses the browser built-in Web Crypto API, and your text is never sent anywhere.
Can I hash passwords with this?
You can hash any text, but for storing passwords use a dedicated password-hashing scheme (like bcrypt) on a server.
