About

This presentation introduces Alternative Checksums in EOS 5.4.0, a feature that enables the storage of multiple hash types for a single file alongside the default system checksum. By allowing for various algorithms, such as MD5 or SHA-256, on a per-directory basis, EOS provides the necessary flexibility to meet diverse experiment requirements.
