Unable to configure Wildcard certificate in Elasticsearch

Elastic Stack Elasticsearch
1

Hi Team,

We are facing issue replacing wildcard certificate with self-signed certificate, due to below issue.

Caused by: java.security.UnrecoverableKeyException: failed to decrypt safe contents entry: javax.crypto.BadPaddingException: Given final block not properly padded.
Such issues can arise if a bad key is used during decryption.

PFB elasticsearch.yml configuration for SSL

xpack.security.http.ssl.keystore.type: PKCS12
xpack.security.http.ssl.keystore.path: /opt/elasticsearch/config/xxxxxx.p12
xpack.security.http.ssl.truststore.path: /opt/elasticsearch/config/xxxxxx.p12
xpack.security.http.ssl.truststore.type: PKCS12
xpack.security.http.ssl.client_authentication: required
xpack.security.http.ssl.keystore.password: xxxxxxxxxx

Please let me know we are using any wrong configuration or missing any configuration commands.

Thanks,
Sathish Thumma.

It doesn't look like you have provided a truststore.password
