SHA-256 checksum
Hash a local file so you can compare it to a published checksum.

Details
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.

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

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

Questions
Does a match prove the file is safe?
It proves the bytes match the hash you were given. It does not prove the publisher is trustworthy.

Why SHA-256 only?
It is the checksum people should be publishing.

Nothing is uploaded. Closing the tab drops the file.
