Hello,
Is this issue from before still a problem with filebeats? Filebeat private key parse error - #6 by adrisr
Also running on openssl version 1.x, when using encrypted pem key with key_passphrase getting:
Exiting: error initializing publisher: 1 error: tls: failed to parse private key
ssl.certificate_authorities: ["/etc/pki/cert"]
ssl.certificate: /etc/pki/logstash.cer
ssl.key: /etc/pki/logstash.key
ssl.key_passphrase: "Password"
I see no problem when Logstash or Elasticearch uses encrypted pem keys
