DataHub Tools Hash Generator

Hash Generator

Local-first

Generate SHA-1, SHA-256, SHA-384, and SHA-512 hashes from UTF-8 text locally in your browser.

What is Hash Generator?

Generate SHA-1, SHA-256, SHA-384, and SHA-512 hashes from UTF-8 text locally in your browser.

  • Generate SHA hashes locally
  • Compare checksum output
  • Copy lowercase hexadecimal digests

How to use it

  1. Paste the exact text whose bytes you want to hash.
  2. Generate SHA-1, SHA-256, SHA-384, and SHA-512 digests.
  3. Compare the same algorithm and text encoding on both systems.
  4. Copy the required digest without adding spaces or line breaks.

Quick example

Example input

DataHub

Expected output

SHA-1, SHA-256, SHA-384, and SHA-512 hexadecimal digests

A hash is not encryption. SHA-1 is included for compatibility checks and should not be selected for new security-sensitive designs.

Best use cases

  • Compare text integrity across systems.
  • Generate SHA-family test vectors for development.
  • Check whether two exact UTF-8 text inputs produce the same digest.

Reference standards and behavior

NIST FIPS 180-4 specifies SHA-1 and the SHA-2 family. This page exposes browser Web Crypto digests and does not provide keyed HMAC or password hashing.

Sources checked July 24, 2026. Standards can change; review the source pages before formal integration.

Notes

  • Whitespace, case, normalization, and line endings change the digest.
  • This page hashes UTF-8 text, not uploaded files.
  • Password storage requires a dedicated password-hashing scheme, not a fast general-purpose hash.

FAQ

Does it support MD5?

No. The page outputs SHA-1, SHA-256, SHA-384, and SHA-512.

Should SHA-1 be used in a new security design?

No. SHA-1 is present for compatibility checks; use an appropriate SHA-2 algorithm for new designs.

Can this hash files?

No. It hashes the exact UTF-8 bytes of pasted text only.

Why did one extra line break change the digest?

Every byte matters, including whitespace, case, Unicode normalization, and line endings.

Can I store passwords with these hashes?

No. Password storage requires a salted, deliberately slow password-hashing scheme.
