Linux 中的 SSL 验证失败

Question

我正在使用 Titanium Web 代理修改 headers 的 https 请求。它在 Windows 中工作正常，但在 Linux 中它失败并出现 alert handshake failure 错误。

我已经使用以下命令生成了根 CA 证书。

openssl genrsa -out rootCert.key 4096
openssl req -x509 -new -nodes -key rootCert.key -sha256 -days 1024 -out rootCert.crt
openssl pkcs12 -export -out rootCert.pfx -inkey rootCert.key -in rootCert.crt

并使用以下命令安装生成的证书。还要确保我的证书文件正确附加到 /etc/ssl/certs/ca-certificates.crt 文件。

sudo cp rootCert.crt /usr/local/share/ca-certificates/
sudo update-ca-certificates

Answer 1

很难给出明确的答案，但我认为问题出在您生成的证书上。尝试添加 -addext 参数并将主题备用名称设置为您的目标主机名。例如，对于 'example.com' 域：

openssl req -x509 -new -nodes -key rootCert.key -sha256 -days 1024 \
    -out rootCert.crt -addext "subjectAltName = DNS:example.com"

或者，如果您想使用根证书，您可以运行没有 rootCert.pfx 文件的 Titanium 服务，它应该会生成一个。然后您可以提取 PEM 证书并将其添加到 ca-certificates:

openssl pkcs12 -in rootCert.pfx -out rootCert.crt -clcerts -nokeys

信任根证书后，Titanium 生成的所有证书都应该有效。
