Hash Generator

Generate cryptographic hashes (SHA-256, SHA-512, SHA-1) from text or files. Compare hashes to verify data integrity. Uses the Web Crypto API — nothing leaves your browser.

What is a Hash?

A hash function takes input data and produces a fixed-size string of characters. Even a tiny change in input produces a completely different hash. Hashes are used for:

\u2022 Data integrity — verify files haven't been tampered with
\u2022 Password storage — store hashes instead of plain passwords
\u2022 Digital signatures — sign and verify documents
\u2022 Checksums — detect data corruption during transfer

How to Use

  1. Type or paste text to generate hashes instantly.
  2. Copy any hash format you need (SHA-256, SHA-512, SHA-1).
  3. Compare by pasting a known hash to verify it matches.
  4. Upload a file to generate its SHA-256 checksum.
