Creating checksums of individual files

Using the web UI of Sunet Drive, you can create checksums of individual files that have been uploaded. This allows users to create a hash checksum of an individual file. The available algorithms are: md5, sha1, sha256, sha384, sha512, sha3-256, sha3-512 and crc32.

1. Open the details view (sidebar) of a file
2. Select the tab “Checksum”
3. Select the algorithm
4. The checksum will be calculated and displayed

Note: This app provides the essential functionality to calculate the checksum for an individual file. No checksums are saved, and if a file changes you might have to reload the page and recalculate the checksum. If you want to calculate checksums for many files, it is recommended to use a synchronization client and a local script. Contact your data office or data steward if your project requires this functionality.
