Jan Høydahl created SOLR-12778:
----------------------------------
Summary: Support encrypted password for ZK cred/ACL providers
Key: SOLR-12778
URL: https://issues.apache.org/jira/browse/SOLR-12778
Project: Solr
Issue Type: New Feature
Security Level: Public (Default Security Level. Issues are Public)
Components: SolrCloud
Reporter: Jan Høydahl
The {{VMParamsSingleSetCredentialsDigestZkCredentialsProvider}} takes a
{{zkDigestPassword}} in as a plain-text JVM param, and the
{{VMParamsAllAndReadonlyDigestZkACLProvider}} takes both {{zkDigestPassword}}
and {{zkDigestReadonlyPassword}}.
Propose to give an option to encrypt these password using the same mechanism as
DIH does:
# Add a new VM param "zkDigestPasswordEncryptionKeyFile" which is a path to a
file holding the encryption key
# Store an encryption key in above mentioned file and restrict access to this
file so only Solr user can read it.
# Encrypt the ZK passwords using the encryption key and provide the encrypted
password in place of the plaintext one
We could also create a utility command that takes the magic out of encrypting
the pw:
{noformat}
bin/solr util encrypt [-keyfile <file>] <string>{noformat}
