Common questions
Good to know
Answers specific to this tool and its current capabilities.
What is a file hash?+
It is a fixed-length digest used to compare file contents and detect accidental changes.
Which hash algorithms are available?+
You can generate SHA-256, SHA-384 or SHA-512 using the browser's cryptographic API.
Does matching a published hash prove a file is unchanged?+
A matching cryptographic digest gives strong evidence that the bytes match the expected file.
