Type or paste text and get every digest in the same view. Compare checksums from a download page, a CMS field, or a legacy system that still prints MD5 next to SHA-256 without running five CLI commands.
Input is hashed as UTF-8 bytes, which is what you want for normal text. Switch to uppercase hex when a spec or a Windows tool shows A–F in capitals. Input byte count is shown so you can confirm leading/trailing spaces.
MD5 and SHA-1 are fine for non-security checksums and terrible as password hashes. SHA-256 and friends are one-way fingerprints, not encryption. Use this generator to verify integrity or to match a documented digest — not to “secure” a login database.
The text never uploads. That matters when you are checksumming a string that includes an API token or a customer id. No account and no file upload.
Checksums update as you type. Watch the input byte count if leading spaces would change the digest.
Each algorithm has its own hex output. Copy the one the other system asked for — download pages often still show MD5 plus SHA-256.
Some tools print digests in capitals. Enable uppercase hex so you can compare without case-folding by eye.
Copy a single hash into your notes or a verify form. Nothing is stored on a server.
