Dongjin Lee commented on KAFKA-12703: ------------------------------------- [~trobador] It seems like you are right. According to [KIP-651|https://cwiki.apache.org/confluence/display/KAFKA/KIP-651+-+Support+PEM+format+for+SSL+certificates+and+private+key] which introduced 'ssl.key.password', it states "If the key is encrypted, key password must be specified using 'ssl.key.password'." In other words, it allows key password may not be specified. [~rsivaram] [~omkreddy] Could you have a look? I thought you must be the best reviewer since you wrote or reviewed the KIP. > Unencrypted PEM files can't be loaded > ------------------------------------- > > Key: KAFKA-12703 > URL: https://issues.apache.org/jira/browse/KAFKA-12703 > Project: Kafka > Issue Type: Bug > Components: clients > Affects Versions: 2.8.0 > Reporter: Brian Bascoy > Priority: Major > > Unencrypted PEM files seem to be internally [supported in the > codebase|https://github.com/apache/kafka/blob/a46beb9d29781e0709baf596601122f770a5fa31/clients/src/main/java/org/apache/kafka/common/security/ssl/DefaultSslEngineFactory.java#L509] > but setting an ssl.key.password is currently enforced by createKeystore (on > DefaultSslEngineFactory).
