Note: All hashing is performed locally in your browser. Your text, file, or secret keys are never sent to any server.

How to use the SHA-256 Generator

Follow these steps to generate a secure SHA-256 hash:

  1. Choose between Text String or File Upload mode.
  2. Enter your data or upload the file you wish to hash.
  3. The SHA-256 hash will be generated instantly in your browser.
  4. You can also enable HMAC mode to use a secret key for added security (available for SHA algorithms).
  5. Verify your hash by pasting another hash in the comparison field.

What is SHA-256?

SHA-256 (Secure Hash Algorithm 256-bit) is a signature for a text or a data file. It is a cryptographic hash function that produces a 256-bit (32-byte) hash value, typically rendered as a hexadecimal number. It is one of the most widely used hash functions for security and data integrity.

Security Reminder: Our generator is entirely client-side. Your inputs and generated hashes never leave your computer, ensuring complete privacy.
