java - Kafka 不会从 PEM 证书开始

Question

我发现 Kafka 2.7.0 支持 PEM 证书，因此我决定尝试使用 DigiCert SSL 证书设置代理。我使用了新的选项，我做了所有的事情，就像 KIP-651 中的例子一样。 .但我得到了错误:

[2021-01-20 17:54:55,787] ERROR [KafkaServer id=0] Fatal error during KafkaServer startup. Prepare to shutdown (kafka.server.KafkaServer)
org.apache.kafka.common.config.ConfigException: Invalid value javax.net.ssl.SSLHandshakeException: no cipher suites in common for configuration A client SSLEngine created with the provided settings can't connect to a server SSLEngine created with those settings.

openssl x509 -in certificate.pem -文本:

Certificate:
    ...
    Signature Algorithm: ecdsa-with-SHA384
        ...
        Subject Public Key Info:
            Public Key Algorithm: id-ecPublicKey
                Public-Key: (256 bit)

我尝试过使用不同版本的 Oracle JDK 和 OpenJDK，但没有效果。
我还尝试使用选项设置证书:

ssl.keystore.type=PEM
ssl.keystore.location=/opt/kafka/certs/certificate.pem
ssl.key.password=null

我得到了一个新错误:

但是如果将此证书转换为 jks:

openssl pkcs12 -export -in certificate.pem -out certificate.p12
keytool -importkeystore -srckeystore certificate.p12 -srcstoretype pkcs12 -destkeystore certificate.jks

echo 'ssl.keystore.location=/opt/kafka/certs/certificate.jks' >>server.properties
echo 'ssl.keystore.password=password' >>server.properties

经纪人工作正常。
这可能是一个错误还是我做错了什么？完整日志 here

我认为这可能是因为您使用的私钥是使用 PBES2 方案加密的。您可以使用 OpenSSL 转换原始 key 并改用 PBES1:

openssl pkcs8 -in old_kafka.key -passout "pass:password" -topk8 -v1 PBE-SHA1-3DES -out kafka.key

您可以找到更多信息其中 PKCS#5加密算法可用于 OpenSSL's PKCS#8 man page 中的 PBES1 和 PBES2 .
此外， this issue 中提到了 OpenJDK 中的 PBES2 支持。 .
