openssl 创建证书和 key

Question

[OpenSSL v1.1.0f]

我正在使用以下命令创建自签名证书，仅用于测试目的:

$ openssl req -x509 -newkey rsa:4096 -keyout key.pem -out cert.pem -days 10000 -nodes

但是我收到这样的消息:

Can't open /usr/local/ssl/openssl.cnf for reading, No such file or directory
140480609138432:error:02001002:system library:fopen:No such file or directory:crypto/bio/bss_file.c:74:fopen('/usr/local/ssl/openssl.cnf','r')

我能做些什么来解决这个问题？

通常 openssl 会使用默认配置，但似乎您没有在正确的位置使用它。您还可以将配置文件作为命令行参数传递。请注意 -config 选项。

openssl req -x509 -config openssl.cnf -newkey rsa:4096 -keyout key.pem -out cert.pem -days 10000 -nodes
