This app provides a collection of SHA-256 and SHA-512 checksums for popular software. You can use this web-based or desktop application to verify the integrity of software downloaded from the internet. You can also store the SHA-256 checksums of your personal files and later use the app to verify them.

Your file will not be uploaded to the server. Its SHA-256 and SHA-512 checksums will be calculated on the client side. Only the checksums and the file name will be sent to the server for verification.
