I know of no smooth workaround for this because most checksums work not on the logical data items, but on their underlying representation.
This is a very high priority feature for the next release of Daffodil 3.2.0 as everyone is hitting this limitation now for CRCs, checksums, and parity calculations when cybersecurity filters want to redact data. There will be a design note about this and how it will work, and your feedback on that will be most helpful. When it comes out we'll be sure to post a link to it here to gather feedback. ________________________________ From: Kyle Rosales <[email protected]> Sent: Tuesday, June 29, 2021 9:49 AM To: [email protected] <[email protected]> Subject: Checksum assistance/example Hello, I am seeking advice on how to generate a checksum. I saw there is an open story for this https://issues.apache.org/jira/browse/DAFFODIL-2221, but I wanted to know if there is a workaround for now to generate one. Thank you, Kyle
