Currently tektoncd/chains uses `Deprecated` in-toto/in-toto-golang `Subject`, `StatementHeader`, etc. structs.

Currently tektoncd/chains uses deprecated https://github.com/in-toto/in-toto-golang structs:

• intoto.Subject{...}
• intoto.StatementHeader{...}
  • intoto.ProvenanceStatementSLSA1{...}
  • intoto.StatementInTotoV01{...}

https://github.com/in-toto/in-toto-golang/commit/32351740df5f3e9c079d4fe12bcf27271e2290b1

https://github.com/in-toto/in-toto-golang/blob/master/in_toto/attestations.go#L32-L42

We should update tektoncd/chains code to use the correct structs

With the work we did in https://github.com/tektoncd/chains/pull/1111 and https://github.com/tektoncd/chains/pull/1118, we migrated the structs to the non-deprecated versions. I think it should be fine to close this issue @chitrangpatel

agreed!
