About Hash Generator

Generate cryptographic hashes using the SHA-256 or SHA-512 algorithm via the browser's built-in Web Crypto API. Enter any text and instantly get its hash fingerprint. Useful for verifying data integrity, storing passwords (with a proper salt), and generating checksums.

How to use

  1. Type or paste the text you want to hash into the input panel.
  2. Select the hashing algorithm (SHA-256 or SHA-512).
  3. Click Generate to compute the hash.
  4. Click Copy to copy the hash to your clipboard.

Frequently Asked Questions

FAQs about Hash Generator

What is a cryptographic hash?

A cryptographic hash is a fixed-size fingerprint of input data. Any change to the input, even a single character, produces a completely different hash. Hashes are one-way — you cannot recover the original input from the hash.

What is SHA-256 used for?

SHA-256 is used for file integrity verification, digital signatures, blockchain (Bitcoin uses SHA-256), TLS certificates, and password storage (with a salt).

Is this tool safe to use with sensitive data?

All hashing is performed locally in your browser using the Web Crypto API. No data is sent to any server.

Can I use this to check if two strings are the same?

Yes. If two inputs produce identical hashes with the same algorithm, the inputs are identical.

Why is MD5 not included?

MD5 is considered cryptographically broken and is not supported by the browser Web Crypto API. SHA-256 and SHA-512 are the modern, secure alternatives.
