SHA-256 checksum

Hash a local file so you can compare it to a published checksum.

Files over 80 MB are refused. SHA-1 and MD5 are not offered.

Hash a file you already have and compare the SHA-256 value with the one published beside a download. Files over 80 MB are refused. SHA-1 and MD5 are not offered. A match means the bytes match. It does not mean you trust the publisher.

  1. 1Drop a file.
  2. 2Wait for the hash.
  3. 3Copy it and compare it to the value from the publisher.

Questions

Why SHA-256 only?
It is the checksum people should be publishing.
Nothing is uploaded. Closing the tab drops the file.
The hash is computed here.
