Free Online Hash

Calculate the cryptographic hash of any text using several algorithms at once: SHA-256, SHA-1, SHA-384 and SHA-512, plus Base64 encoding. Hashes are computed with the browser's native Web Crypto API (crypto.subtle), the same one web apps use to verify data integrity, without sending your text to any server.

Why use Hash

  • Calculates SHA-256, SHA-1, SHA-384 and SHA-512 at the same time
  • Includes Base64 encoding alongside the cryptographic hashes
  • Uses the browser's native Web Crypto API, not an external library
  • Your text never leaves your browser
  • Instant result, copy each hash with one click

How to use it in 3 steps

  1. 1

    Type or paste your text

    Enter the content you need to hash.

  2. 2

    Check the generated hashes

    SHA-256, SHA-1, SHA-384, SHA-512 and Base64 are calculated automatically.

  3. 3

    Copy the one you need

    Click the corresponding hash to copy it.

Questions about Hash

What hash algorithms does this tool calculate?

SHA-256, SHA-1, SHA-384 and SHA-512, computed with the browser's Web Crypto API. It also includes Base64 encoding, which is not a hash but a reversible encoding.

Does it calculate an MD5 hash?

No. MD5 isn't available in browsers' Web Crypto API because it's an outdated, insecure algorithm; this tool uses SHA-256, SHA-1, SHA-384 and SHA-512 instead.

Is my text sent to a server to calculate the hash?

No, the entire calculation happens in your browser using the native cryptography API.

What is calculating a hash useful for?

For verifying a file's or text's integrity, generating unique identifiers from content, or comparing whether two texts are identical without revealing their content.

Is Hash free?

Yes, Hash from WebHerramientas is 100% free. No registration or subscription required. You can use it as many times as you need at no cost.

Is it safe to use Hash online?

Yes, all information is processed directly in your browser. We do not store or send your data to any external server.

Does Hash work on mobile?

Yes, the tool is fully responsive and works on any device: phone, tablet or computer with a modern browser.
