Hash Generator — SHA-256 SHA-512 Online | MyToolbox

Generate SHA-1, SHA-256, SHA-384, and SHA-512 hashes instantly. Free hash generator for developers. Runs in your browser.

How to Use Hash Generator

1

Enter your text

Type or paste the text you want to hash into the input field.
2

See all hashes

All supported hash algorithms produce output simultaneously: SHA-1, SHA-256, SHA-384, and SHA-512. No need to select one first.
3

Copy the hash you need

Click copy next to any hash value to place it on your clipboard.

Why Use Our Hash Generator

Multiple Algorithms

SHA-1, SHA-256, SHA-384, and SHA-512 — all computed simultaneously. Compare hash outputs across algorithms at a glance.

Instant Computation

Hashes are calculated in real time as you type. No need to click a button — results update with every keystroke.

Web Crypto API

Uses the browser's native Web Crypto API (SubtleCrypto) for fast, standards-compliant hash computation.

Hex Output

Hash values are displayed in standard hexadecimal format, ready for use in code, verification, and configuration.

Completely Private

All hashing happens in your browser. Your input data is never transmitted — critical when hashing passwords, keys, or sensitive data.

Frequently Asked Questions

Is the hash generator free?

Yes, completely free. No limits on usage, no signup, and no ads.

Is my data safe when generating hashes?

Yes. All hash computation happens in your browser using the Web Crypto API. Your input text is never sent to any server.

What hash algorithms are available?

SHA-1, SHA-256, SHA-384, and SHA-512. All four are computed simultaneously for your input.

Can I use this to verify file integrity?

Yes. Paste the text content and compare the generated hash against the expected value. For file hashing, copy the file content as text into the tool.

How does this compare to tools like CyberChef?

CyberChef is a comprehensive data transformation toolkit. MyToolbox is focused specifically on hash generation with a simpler interface — faster for quick hashing tasks.

Which algorithm should I use?

SHA-256 is the most widely used for general purposes. SHA-1 is considered weak for security but is still used for checksums. SHA-512 offers the highest security margin.

Does this work offline?

Yes. Once the page is loaded, hash computation works without an internet connection.

Are the hashes identical to what programming languages produce?

Yes. The Web Crypto API produces standard hash outputs. The SHA-256 hash of any string here will match the output of hashlib.sha256 in Python, crypto.createHash in Node.js, or any other standard implementation.
