How to Generate Hashes
The Hash Generator computes cryptographic hashes (MD5, SHA-1, SHA-256, SHA-512) for any text using the browser's Web Crypto API.
- Type or paste the text you want to hash.
- View all hash outputs (MD5, SHA-1, SHA-256, SHA-512) computed simultaneously.
- Copy any hash value with one click.
What Is a Cryptographic Hash?
A hash function takes an input of any size and produces a fixed-length output (the hash or digest). The same input always produces the same hash, but even a tiny change produces a completely different output. Hashes are used for password storage, data integrity checks, digital signatures, and file deduplication. SHA-256 is the most widely used secure hash today.
Why Use Our Hash Generator?
- Multiple algorithms — MD5, SHA-1, SHA-256, and SHA-512 side by side.
- Web Crypto powered — uses the browser's native cryptographic API for speed and security.
- Instant — hashes compute as you type.
- Private — your input never leaves the browser.
Frequently Asked Questions
Is MD5 still safe to use?
MD5 is cryptographically broken — collisions can be generated easily. Do not use it for security purposes (passwords, signatures). It is still acceptable for non-security checksums like file deduplication.
Which hash should I use for passwords?
None of these — passwords should use a purpose-built algorithm like bcrypt, scrypt, or Argon2 that includes salting and intentional slowness. SHA-256 is for data integrity, not password storage.
Can I hash files?
This tool hashes text input. For file hashing, you would need to read the file as bytes first. File hash support may be added in the future.
Is my data private?
Yes. All hashing happens in your browser via the Web Crypto API. No data is transmitted.
