OS X:拒绝客户端证书的Git

Question

我们通过在〜/ .gitconfig中添加以下行来访问带有客户端证书的Git服务器

[http]
        sslCAInfo = /path/to/git-ca.crt
        sslCert = /path/to/git-client.crt
        sslKey = /path/to/git-client.pem

这适用于Linux,Windows和OS X <= 10.8,文件完全相同.当我在OS X 10.10上尝试它时,我收到以下错误:

bash-3.2$ git fetch
fatal: unable to access 'https://ourserver:12345/repository.git/': SSL: Can't load the certificate "/path/to/git-client.crt" and its private key: OSStatus -25299

问题既发生在git version 1.9.3 (Apple Git-50),也发生在git version 2.0.1.

更新 从KeyChain中删除相应的项目后,我遇到了以下崩溃:

此次崩溃后,证书条目已在Keychain中重新发生.奇怪的是,在OS X 10.8上,从存储库中取出时,我的钥匙串不会添加任何内容.

更新2 当我在OS X 10.9上尝试相同时,我收到以下错误:

bash-3.2$ git fetch
fatal: unable to access 'https://ourserver:12345/repository.git/': SSL certificate problem: Invalid certificate chain

更新3openssl即使在OS X 10.9上, 我也可以使用这些证书成功连接:

bash-3.2$ openssl s_client -connect ourserver:12345 -cert /path/to/git-client.crt -key /path/to/git-client.pem

问题与GitHub的问题类似,但我们使用的是自签名证书.

Answer 1

看起来您遇到了与此docker问题相同的问题,他们认为这可能是OSX卷曲中的一个错误.

在其他一些帖子中,他们建议,这可能是由于证书序列号为1或太大而不适合32位.

在您的OS X 10.9案例中,我认为应该通过将证书添加到受信任的系统密钥链来解决"无效证书"(在本问题中讨论).

这篇文章描述了OS X curl的一些变化,这似乎是相关的.根据我的理解,切换到不同的curl实现可能是解决方案(但是如果git也可以使用brew安装,那么可能只会有效).
