SHA-256 Checksum Calculator
Ready.
How to use
Choose a file or enter text, calculate SHA-256, then compare the hexadecimal digest with the trusted reference value.
Privacy
Files and text are hashed by the browser Web Crypto API and are not uploaded to our server.
Limitations
A matching checksum verifies byte equality with the reference; it does not prove that the reference itself is trustworthy.
Example
Compare a downloaded installer SHA-256 value with the checksum published by the official vendor.
