Issues in configuring searchguard.ssl.transport.pemkey_password

shivani.aggarwal2195 · June 16, 2020, 6:01pm

Elasticsearch version: : 7.0.1
Describe the issue: - Unable to configure self signed certs (in pem format) for searchguard.ssl.transport when key is encrypted.

When I generate certificates with -nodes flag (i.e. avoiding encryption of key), I am able to setup SG successfully.

openssl req -x509 -newkey rsa:4096 -keyout node.key.pem -out node.crt.pem -days 365 -subj “/C=IN/CN=elasticsearch.shiv” -nodes ----> Working fine

When the same cmds are used without nodes flag (with encryption of key), the setup is failing.

Steps used to generate self-signed certs:

Node cert (passphrase of key when prompted - “eskey”)

openssl req -x509 -newkey rsa:4096 -keyout node.key.pem -out node.crt.pem -days 365 -subj “/C=IN/CN=elasticsearch.shiv”

Admin cert (passphrase of key - “adminkey” )

openssl req -x509 -newkey rsa:4096 -keyout admin.key.pem -out admin.cert.pem -days 365 -subj “/C=IN/CN=admin”

Rootca

cat node.cert.pem admin.cert.pem > root-ca.pem

Provide configuration:

searchguard.ssl.transport.pemkey_filepath: "/etc/elasticsearch/certs/node.key.pem"
searchguard.ssl.transport.pemcert_filepath: "/etc/elasticsearch/certs/node.crt.pem"
searchguard.ssl.transport.pemtrustedcas_filepath:"/etc/elasticsearch/certs/root-ca.pem"
searchguard.ssl.transport.pemkey_password: "eskey"

Provide logs:

Caused by: java.lang.IllegalArgumentException: File does not contain valid private key: /etc/elasticsearch/certs/node.key.pem

But I checked the validity of the key -

$ openssl rsa -in node.key.pem -check
Enter pass phrase for es-key.pem: ( “eskey”)
RSA key ok
writing RSA key…

Since one log msg suggested to remove key password if provided, I removed the parameter searchguard.ssl.transport.pemkey_password: “eskey” from the configuration and restarted. With this, I get this error -

Can someone pls explain the right way to configure searchguard.ssl.transport.pemkey_password parameter? And if the steps used to generate/configure certs should be modified?

Thanks!

First, create the TLS certificates using the Search Guard TLS tool docs/tls.md · master · search-guard / labs · GitLab

Then the config for a cluster node can be:
elasticsearch.yml

node.name: sgssl-0.example.com
network.host: 0.0.0.0
http.port: 9200
cluster.name: es-docker-cluster
discovery.seed_hosts: ["sgssl-1.example.com", "sgssl-2.example.com"]
cluster.initial_master_nodes: ["sgssl-0.example.com", "sgssl-1.example.com", "sgssl-2.example.com"]
bootstrap.memory_lock: true
cluster.routing.allocation.disk.threshold_enabled: false
node.max_local_storage_nodes: 3

xpack.security.enabled: false

searchguard.allow_default_init_sgindex: true
searchguard.audit.type: internal_elasticsearch
searchguard.enable_snapshot_restore_privilege: true
searchguard.check_snapshot_restore_write_privileges: true
searchguard.restapi.roles_enabled: ["SGS_ALL_ACCESS"]
# This is a configuration snippet for the node node1
# This snippet needs to be inserted into the file config/elasticsearch.yml of the respective node.
# If the config file already contains SearchGuard configuration, this needs to be replaced.
# Furthermore, you need to copy the files referenced below into the same directory.
# Please refer to http://docs.search-guard.com/latest/configuring-tls for further configuration of your installation.

You cant try it in docker using this repo Files · master · search-guard / labs · GitLab

This error may arise from this Java bug Loading...

The solution is to use the v1 encryption scheme. With openssl use the -v1 flag, for example openssl pkcs8 -in key.pem -topk8 -out enckey.pem -v1 PBE-SHA1-3DES
