Cpp VPC-SSL demo 一直报SSL错误

使用的就是ca-cert.pem,跟运行程序放在同一目录。

I have this problem too, did you solve it?

请尝试重新下载demo进行测试。我目前测试是OK的

我用openssl的s_client命令测试了SSL，用demo里的证书去连我的kafka broker，发现SSL握手失败的原因是因为我的openssl编译的时候默认的TLS安全等级是2（不算特别高），但是这个证书里面的密钥长度仅1024，加密算法是sha1（早已满足不了今日的安全需求），这个1024bit密钥+sha1算法是不满足openssl TLS安全等级2的要求的，所以会握手失败，如果你一定要用阿里的证书的话，得把运行环境得openssl重新编译一遍，选最低的TLS安全等级(https://www.openssl.org/docs/man1.1.1/man3/SSL_CTX_set_security_level.html )， 不过说实话选这么低等级的安全等级SSL就变得很鸡肋了
