Online Hash Generator — Free MD5, SHA-1, SHA-256, SHA-512 Hasher
What is a Hash Generator?
A hash function converts any text input into a fixed-length string of characters. It's deterministic (same input always produces the same hash), one-way (you can't reverse it), and is used for password storage, file integrity checks, and digital signatures.
Our hash generator supports SHA-256 (the industry standard), SHA-1, SHA-384, SHA-512, and MD5 (for legacy use).
Why Use Our Hash Generator?
- Multiple algorithms — SHA-256, SHA-1, SHA-384, SHA-512, and MD5
- Cryptographic-grade — Uses the browser's native SubtleCrypto API
- 100% private — Your data is never sent to any server

Frequently Asked Questions
Is MD5 still safe to use?
MD5 is considered cryptographically broken and should not be used for security purposes. Use SHA-256 or stronger for any security-critical applications.
Is my data secure?
Yes. All hashing happens in your browser. Your input text never leaves your device.
