फ़ाइल चेकसम.

One file up to 25 MB. Requires a secure browser context such as HTTPS or localhost.

A checksum changes when the file’s bytes change, making it useful for integrity comparison. A matching hash is only meaningful when the expected value comes from a trusted source. Hashing does not scan for malware or prove who created the file.

Compare a downloaded file’s SHA-256 with the publisher’s checksum.
