About Hash Generator

Compare deterministic text digests while debugging or checking whether two exact strings match.

How to use it

  1. Choose SHA-256 or SHA-512.
  2. Paste the exact text you want to hash, including any intentional spaces or newlines.
  3. Run the tool, then copy or download the hexadecimal digest.

Good to know

  • Hashing is not encryption and there is no decode operation. A plain SHA digest is not a password-storage scheme.
  • This tool hashes UTF-8 text, not uploaded files. Even a single changed space or newline changes the digest. A secure browser context is required.
