我正在尝试使用命令行工具通过ssl连接,以使用0.11.0.3kafka版本的用户身份删除kafka代理,连接字符串如下

kafka-console-consumer.bat \
    --bootstrap-server host:port \
    --topic topicName \
    --from-beginning \
    --group groupId \
    --consumer.config ssl.properties
``` `ssl.properties` 文件

security.protocol=SSL
ssl.truststore.location=path/to/truststore.jks
ssl.truststore.password=1234567
ssl.keystore.location=path/to/keystore.jks
ssl.keystore.password=1234567
ssl.key.password=1234567
ssl.enabled.protocols=TLSv1.2,TLSv1.1,TLSv1
ssl.truststore.type=JKS
ssl.keystore.type=JKS

我得到一个例外

你知道为什么会这样吗?是证书问题吗?我没有生成它们,它们是Kafka服务器所有者给我的。提前谢谢。

您的代理的证书中似乎缺少subject alternative name(san)(例如 /var/private/ssl/kafka.server.truststore.jks ).
为此,请附加参数 -ext SAN=DNS:{FQDN} 对于keytool命令:

keytool \ 
    -keystore kafka.server.keystore.jks \
    -alias localhost \
    -validity {validity} \
    -genkey \
    -keyalg RSA \
    -ext SAN=DNS:{FQDN}

确保在创建服务器的密钥库时包含san。confluent的安全教程中也提到了这一点:
如果启用了主机名验证,则客户端将根据以下两个字段之一验证服务器的完全限定域名(fqdn):
通用名(cn)
使用者备用名称(san)
这两个字段都有效,但是rfc-2818建议使用san。san也更灵活,允许声明多个dns条目。另一个优点是,可以将cn设置为更有意义的值,以用于授权目的。
或者,您可以选择禁用服务器主机验证:
通过设置禁用服务器主机名验证 ssl.endpoint.identification.algorithm 一个空字符串。
因此,你只需要开始 server.properties 执行以下配置并最终重新启动kafka群集:

ssl.endpoint.identification.algorithm=
rfbsl7qr

rfbsl7qr2#

请注意,在生成密钥对(以及密钥存储)时仅包含“san”是不够的。

keytool \ 
    -keystore kafka.server.keystore.jks \
    -alias {alias} \
    -validity {validity} \
    -genkey \
    -keyalg RSA \
    -ext SAN=DNS:{FQDN}

在创建证书签名请求时,还需要包含“san”。

keytool \ 
    -keystore kafka.server.keystore.jks \ 
    -alias {alias} \ 
    -certreq -ext SAN=DNS:{FQDN} 
    -file {csr_filename}

可以验证由此创建的证书签名请求,并且它应该具有相关的san。

keytool \ 
    -v -printcertreq -file {csr_filename}

稍后,如果使用openssl的x509命令来完成证书签名请求,则应注意显式包含x509版本3扩展。“san”就是这样一个扩展,除非明确包含在内,否则它不会进入最终颁发的证书中。这里详细讨论了这个概念-证书中不存在使用者替代名称。
