Generated files for same chunk differ in binary
See original GitHub issueAfter running the testdata profile twice, I noticed that the same file for the same chunk differs on byte level, although the file size is identical. This should not happen, as it will cause problems on CDN.
For the index file, it looks like missing sorting is causing the problem, one example:
[23,18,21,22,19,20]

Managed to convince the ZIP Library to create byte-identical archives. The payload signing creates different bytes for the same chunk each time though. Having the signing algorithm create the same bytes for the same chunk would be a security risk, so we can’t create byte-identical archives for the same chunk.
Since the generation code has changed a lot & Timon and me are working on https://github.com/corona-warn-app/cwa-server/issues/203, we will have an eye on this as well. I will reopen this, in case https://github.com/corona-warn-app/cwa-server/issues/203 will not fix it.
