Hash Generator

Calculate MD5, SHA-1, SHA-256, SHA-384 and SHA-512 hashes of text or files. Uses the Web Crypto API and runs fully offline in your browser.

Runs locally — your input never leaves this page.

How to use

  1. Type or paste text — all hashes update as you type.
  2. Or choose a file to compute its checksum, for example to verify a download.
  3. Switch between lowercase and uppercase hex output and copy any hash with one click.

FAQ

Can a hash be reversed?

No. Hash functions are one-way. However, short or common inputs can be found with lookup tables, so never store plain hashes of passwords — use bcrypt, scrypt or Argon2.

Is MD5 still safe?

MD5 and SHA-1 are broken for security purposes (collisions can be produced). They are fine for non-security checksums; use SHA-256 or better for anything security-related.
