Hash text online

Compute a SHA-256, SHA-1, or MD5 digest of any text — to verify a download's integrity, compare two values, or generate a stable key — all locally.

The problem

You need a hash: to confirm a file or string matches a published checksum, to compare two values without storing them, or to derive a stable cache key. Computing it locally gives you the digest without installing a CLI or sending the text anywhere.

Sample input

Text
hello

Expected output

Digests
SHA-256: 2cf24dba5fb0a30e26e83b2ac5b9e29e1b161e5c1fa7425e73043362938b9824
MD5:     5d41402abc4b2a76b9719d911017c592

Hashing is one-way: the same input always gives the same digest, but you cannot reverse the digest back to the text. SHA-256 is preferred; MD5 is shown for legacy checksums only.

How to do it

  1. Paste the text to hash.
  2. Choose the algorithm, such as SHA-256.
  3. Compute the digest.
  4. Compare it to an expected checksum if you have one.
  5. Copy the digest.

Common mistakes

  • Using MD5 or SHA-1 for security instead of integrity-only checks.
  • Hashing with a trailing newline that changes the digest.
  • Comparing digests in different cases or with spaces.
  • Expecting to reverse a hash back to the input.
  • Treating a fast hash as safe for storing passwords.

FAQ

How do I hash text?

Paste the text, choose an algorithm such as SHA-256, and compute. The tool returns the hex digest, which is the same every time for the same input.

Can I reverse a hash to get the text back?

No. Hashing is one-way. You can only recompute the hash of a candidate input and compare, not invert the digest.

Should I use MD5?

Only for non-security checksums against legacy systems. MD5 and SHA-1 are broken for security; use SHA-256 when integrity matters.

Why does my hash not match the published one?

Often a trailing newline or different character encoding changed the input. Hash the exact bytes, and compare digests case-insensitively in hex.

Is my text uploaded?

No. Hashing runs locally in your browser. Your text is not sent to a server.

Hashing runs locally in your browser. Your text is not uploaded.
