Hash Generator

Hash Generator

Generate MD5 and SHA-256 hashes from any text using Web Crypto — private, instant checksums.

Your data never leaves your browser — all processing happens locally on your device.

Algorithm

SHA-256 uses the Web Crypto API. MD5 is provided for legacy checksums — not for passwords.

Enter text and click Generate hash.

About this tool

The Hash Generator computes MD5 and SHA-256 digests from text for checksums, debugging and data integrity checks. SHA-256 uses the browser's Web Crypto API; MD5 is included for legacy compatibility. Your input is never uploaded — hashing runs entirely on your device.

  2. 2

    Enter your text

    Type or paste the string to hash.

  3. 3

    Generate and copy the hex digest.

Frequently Asked Questions

Is MD5 secure for passwords?

No. MD5 is deprecated for security. Use it only for non-security checksums. For passwords, use the Password Generator.

How is SHA-256 computed?

Via the Web Crypto API (crypto.subtle.digest) built into modern browsers.

Is my text stored?

No. Hashing happens locally and nothing is logged or transmitted.
