------------------------------------

             Summary: As part of release, generate a file containing multiple digests
                 Key: CALCITE-1329
                 URL: https://issues.apache.org/jira/browse/CALCITE-1329
             Project: Calcite
          Issue Type: Bug
            Reporter: Julian Hyde
            Assignee: Julian Hyde


Currently as part of the release we generate {{.md5}} and {{.sha1}} digests (as well as the pgp {{.asc}} file) and the download page http://calcite.apache.org/downloads/ references the md5 and pgp but not the sha1.

Per http://www.apache.org/dev/release-signing.html#md5-security md5 is no longer secure, and sha512 is preferred over sha256. The best approach seems to be to generate multiple digests, and generate new ones as best practices change. I think we should generate checksum file with a {{.mds}} suffix as follows:

Apache Ranger already does this; see http://ranger.apache.org/download.html.

We would no longer generate {{.md5}} and {{.sha1}} files, but would continue to generate the {{.asc}} file.
