Subject [jira] [Updated] (JCR-4115) Don't use SHA-1 for new DataStore binaries (Jackrabbit)
Date Tue, 28 Feb 2017 11:26:45 GMT

     [ https://issues.apache.org/jira/browse/JCR-4115?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Amit Jain updated JCR-4115:
---------------------------
    Attachment: JCR-4115c.patch

Attached a patch modifying [~tmueller]'s patch to have the digest algorithm as a system property.
Only place where it needs to go is {{AbstractDataStore}} and all other occurrences can be
removed.

> A collision for SHA-1 has been published. We still use SHA-1 for the FileDataStore, and
I believe the S3 DataStore right now. Given there is a collision, we should switch to a stronger
algorithm, for example SHA-256, for new binaries.
