How to use / FAQ

Type or paste text into the box and every hash updates as you go — MD5, SHA-1, SHA-256, SHA-384, and SHA-512, side by side. Each row has its own copy button. Text is hashed as UTF-8, so results match what a server would produce for the same input.

Which hash should I use?

For file integrity or checksums, MD5 and SHA-256 are the most common. For anything security-sensitive, prefer SHA-256 or stronger — MD5 and SHA-1 are considered broken for collision resistance and are shown here for compatibility with older systems.

Can I reverse a hash back to the original text?

No. Hashing is one-way — the same input always produces the same digest, but there's no way to recover the input from it. That one-way property is exactly what makes hashes useful for checksums and verification.

Why is MD5 available when Web Crypto doesn't support it?

The browser's built-in crypto covers the SHA family but not MD5, so MD5 is computed with a small self-contained implementation. There are still no external libraries and no network calls.

Is my text uploaded anywhere?

No. Every hash is computed in your browser — the text you paste never leaves your device.
