我在Windows 7上也遇到了类似的问题:

WARNING: can't open config file: C:\OpenSSL-Win32\bin\openssl.cfg
Unable to load config info from C:\OpenSSL-Win32\bin\openssl.cfg

原因是在没有使用deinstallator的情况下删除了OpenSSL-Win32目录，所以没有正确地从系统中删除所有组件。 我不得不手动删除环境变量OPENSSL_CONF。

一些openssl二进制文件，例如安装在git中，不需要OPENSSL_CONF环境变量，但是如果这个环境变量存在，它必须指向有效的文件。

对我来说，在调用之前放置变量是可行的:

OPENSSL_CONF=/usr/ssl/openssl.cnf openssl req -new -x509 -key privatekey.pem -out publickey.cer -days 365

如果你使用的是Win32 OpenSSL v1.1.0g，设置这个环境变量:

set OPENSSL_CONF=C:\OpenSSL-Win32\bin\cnf\openssl.cnf

在运行此命令之前，先使用“server. exe”。Key”，成功创建server.csr:

openssl req -new -key server.key -out server.csr

在这种情况下，唯一对我有用的是自己创建的openssl.cnf文件。

以下是练习所需的基本知识(可根据需要编辑):

我希望这对你有所帮助。

使用GnuWin32工具，我在C:\ GnuWin32 \share下找到了openssl.cnf

set OPENSSL_CONF=C:\gnuwin32\share\openssl.cnf

在Windows Powershell上:

$env:OPENSSL_CONF = "${env:ProgramFiles}\OpenSSL-Win64\bin\openssl.cfg"
