Hash Generator — SHA-256, MD5 Online

Generate cryptographic hashes (SHA-256, MD5, etc.) from text locally in your browser.

Developer Direct route, no hidden menu

How It Works

As you type, the tool uses the browser's Web Crypto API to compute SHA hashes instantly. MD5 is computed via a local JS library since it's not natively supported in modern Web Crypto.

Example

Type 'admin' to see its well-known MD5 hash: 21232f297a57a5a743894a0e4a801fc3

When to use a Hash Generator

Verifying file or data integrity.
Creating unique fingerprints for strings.
Testing backend login endpoints requiring hashed passwords.

Supported algorithms

SHA-256 (Recommended, secure)
SHA-512 (Higher security)
SHA-1 (Legacy, deprecated for security)
MD5 (Legacy, fast, not secure)

Frequently Asked Questions

Is the data sent to a server for hashing?

No. All cryptographic hashing is performed locally in your browser using the native Web Crypto API. Your data is secure and private.

Can I reverse a hash?

No. Hashes are mathematically designed to be one-way functions. You cannot derive the original text from the hash.
