Create content addressable files
Caf (content addressable files) is a CLI utility that allows you to:
- Create random files using caf gen
- Verify the generated files have not been tampered with caf verify
That’s it. Generate files with random content and verify the files haven’t changed. The caf gen command gives control over both the number of files to create as well as the size of the files created. It even lets you specify the distribution of file sizes (more on that in a bit).
Caf is also designed in a way that allows for parallel file generation as well as parallel file validation. It can seamlessly scale up to billions of files.
For example, create a set of random files up to 10MB (the default file size is 4k):
$ caf gen --max-disk-usage 10MB
You can then verify the files are all there:
$ caf verify
The --help output of the caf gen command contains many more examples.
Download the file for your platform. If you're not sure which to choose, learn more about installing packages.
