Ishan Chattopadhyaya commented on SOLR-14649:
---------------------------------------------
This is not an immediate danger, because:
# Breaking SHA1 is still prohibitively expensive:
https://wccftech.com/google-cracked-sha1/
# Not many packages are out there
However, because adoption is still low, it is the right time to fix this.
> Package manager should use SHA512, not SHA1

> Key: SOLR-14649
> URL: https://issues.apache.org/jira/browse/SOLR-14649
> Project: Solr
> Issue Type: Improvement
> Security Level: Public(Default Security Level. Issues are Public)
> Reporter: Ishan Chattopadhyaya
> Priority: Major
>
> Due to a massive oversight, we only support SHA1 based package signing. We
> should immediately switch to SHA512. Post that, all existing packages must be
> re-signed with SHA512.
> I'll propose this for a 8.6.1 breakfix release.
