Hi Avarinth, There is an open issue to encrypt index files using AES, don't know if that would fit your requirements: https://issues.apache.org/jira/browse/LUCENE-2228 Regards, András On Tue, Feb 6, 2018 at 8:32 AM, Michael Wilkowski wrote: > Hi, > sorry to say that, but your encryption is not

Hi, sorry to say that, but your encryption is not secure at all. Actually it is very weak. Since you encrypt tokens only (and apply padding) then it is very easy based on the examples above to actually reverse engineer your text. If somebody understands the domain, has text distribution and may bui

Encrypting the _tokens_ inevitably leads to reduced capabilities BTW. Trivial example: I have these tokens in my index run runner running runs Any non-trivial encryption algorithm will not encrypt the first three letters "run" identically in all three so searching for run* simply won't work. As y

Harry Ochiai (Hitachi) has some index encryption solution, https://www.slideshare.net/maggon/securing-solr-search-data-in-the-cloud I think it is proprietary, but I'm not sure. Maybe more googling might help find the exact page where his solution is described. On Mon, Aug 7, 2017 at 9:59 PM, Kumar

No, since you haven't defined what you want to encrypt, what your requirements are, what you hope to get out of "encryption" etc. Put the index on an encrypting filesystem and forget about it if you possibly can, because anything else is a significant amount of work. To encrypt the searchable toke

Encryption in Solr has a bunch of ramifications. Do you care about - encryption at rest or in memory? - encrypting the _searchable_ tokens? - encrypting the searchable tokens per-user? - encrypting the stored data (which a filter won't do BTW). It's actually a fairly complex topic the discussion
