Privacy details

Hash generator checker processes your input in this browser. Inputs and results are excluded from analytics. Recent tools save tool names, visit counts and last-visit times. Saved tools store only their names. Draft saving is optional and stays on this device; delete saved text with the draft controls. Loading text from a URL is optional and contacts that server; its URL and your IP address are visible to the server. An optional “Use in” action keeps a handoff in this tab. The next tool removes it on arrival and ignores it if more than a minute has passed.

Copy link includes the inputs you choose to share in the address. Anyone with that link can reopen them. Files and generated results are excluded. Password and key tools share settings only.

Your result

Reset reloads the tool with its starting values and releases open files and device controls. Saved drafts stay on this device until you delete them.

Links include your inputs and settings. Anyone with the link can see them, so leave out private text. Files and generated results are left out; random draws run again.

Hash generator checker explained

Compute a SHA-256, SHA-384 or SHA-512 digest of the exact UTF-8 text using Web Crypto. Paste an expected hexadecimal digest to compare it locally. Spaces and line endings are part of the input.

A worked example

SHA-256 of abc begins ba7816bf and ends f20015ad. Adding a line break produces a different digest.

Before you use the result

A digest is not encryption or a password-storage scheme. It can compare data but does not authenticate who supplied it. This page hashes text; a text-file import decodes the file as UTF-8.
