PRIVACY · HASHLAB
Your file enters the browser, not a server.
HashLab reads file bytes or text on the current page, calculates a digest with Web Crypto, and leaves the result on the page.
SHA verification
A selected file is read into memory with the browser File API. Text, file bytes, algorithm choice, expected digest, and calculated result are not sent to MiluLand. After refresh or close, HashLab cannot recover them. To protect sensitive content, this tool never saves tool inputs as a workspace.
A digest is not encryption
A hash digest helps detect whether content matches; it is not reversible encryption and does not conceal short, guessable text. A published digest may help others test guesses, so do not treat plain SHA of a password or low-entropy secret as protection.
HMAC keys and copying
The HMAC key and message are used only in page memory for calculation and are not saved by HashLab. A result is written to the system clipboard only after you click copy; this site does not read the clipboard. Copied content is then controlled by the operating system, browser extensions, and other apps.
Display preferences and ads
The site uses .miluland.com domain cookies to sync language, theme, high-contrast preference, and up to 16 favorite tool IDs across MiluLand sites, with a local compatibility copy on the current site. Favorites contain only tool IDs—never inputs, files, or results—and can be cleared from the MiluLand tool directory or browser settings.
This page uses Google AdSense Auto Ads. Third parties may process cookies and ordinary network information such as IP address, browser details, and access time under their policies; HashLab does not intentionally provide files, text, HMAC keys, or digests to the ad system.

Google Analytics measures page visits and tool openings. Visitors in the EEA, UK, Switzerland, mainland China, Canada, South Korea, and Türkiye are asked first; other identified regions start automatically. A previous refusal, GPC, or Do Not Track takes precedence. Tools work with either choice.
We use same-site Cloudflare connection information to determine the country or region, not your language, and do not save the IP address in the lookup. If the lookup fails, the Google tag still starts with regional consent defaults: analytics cookies in consent-required regions await permission, while Google may receive basic cookieless signals. Automatic startup is not recorded as your explicit consent.
Files, filenames, tool inputs, search terms, URL parameters, fragments, and results are excluded. Page names use fixed paths and referrers contain only the source site. Google processes visit identifiers and technical browser information. Enhanced measurement, Google signals, and ad-personalization measurement are disabled.
Turn analytics on or off through Privacy & analytics in the footer. Explicit choices are shared across enabled pages in a .miluland.com cookie for up to 180 days; automatic startup does not save an accepted choice. Turning it off stops this integration and clears accessible GA cookies. Advertising uses separate consent settings.
