Hash Generator

Generate MD5, SHA-1, SHA-256, and SHA-512 hashes from any text using the Web Crypto API.

Cryptographic hashes are one-way functions used for data integrity verification, password storage, digital signatures, and checksums. This tool generates hashes using the Web Crypto API built into modern browsers, ensuring cryptographic-grade output.

Choose from SHA-1, SHA-256, SHA-384, or SHA-512. The output is provided in both hexadecimal and Base64 formats. Everything runs in your browser with no data sent to any server.

  2. Select the hash algorithm
  3. Click Calculate to generate the hash
  4. Copy the hex or Base64 output

FAQ

Why no MD5?

The Web Crypto API does not support MD5. MD5 is also considered cryptographically broken and should not be used for security purposes.

Is SHA-256 secure?

Yes. SHA-256 is part of the SHA-2 family and is widely used in TLS, Bitcoin, and other security protocols. It is considered secure for all practical purposes.

Is my text sent to a server?

No. The Web Crypto API processes everything locally in your browser.
