h5pack checksum documentation
Note
If you're new to h5pack, please consult our Quickstart guide.
Please note that this page is just a quick reference to explain different tool options.
This tool allows you to verify the integrity of your .h5 files by checking that the stored checksum matches the actual checksum value. Additionally, you can use it to regenerate the checksum file if something has changed and you need to update its checksum value. A checksum file is a .sha256 file stored right next to your .h5 file. This file contains a list of files and their corresponding checksum values.
Basic usage
Verifying existing checkpoints
The output should look as follows:
Verifying checksum in 'dataset.sha256' ...
dataset.h5 8258bb92f49c2ed032bbe6f1e3bc86132cbc8b7bc0c0e512c4bc6b9888f9aabe [OK]
Checksum verification completed in 0.2 millisecond(s)
Calculating checksum
If the input has a .h5 extension or is a folder, the checksum of all .h5 files found will be calculated and printed to the screen as follows:
Calculating checksum for .h5 files in 'dataset.h5' ...
dataset.h5 8258bb92f49c2ed032bbe6f1e3bc86132cbc8b7bc0c0e512c4bc6b9888f9aabe
Checksum calculation completed in 0.1 millisecond(s)
Additionally, you can use the --save to save the calculated checksum to a .sha256 file.
Advanced settings
Recursive search
To calculate the checksum of multiple .h5 files, possibly within nested folders, you can use the -r/--recursive flag. Please note that this option is only available for checksum calculations.
