如何使用openssl从pfx文件中提取私钥? [英] How to extract private key from pfx file using openssl?

问题描述

我一直在寻找这个私钥，以便在Softlayer的添加证书"向导中添加ssl证书，并将其进一步与Local Load Balancer结合使用.

I was looking for this private key to add ssl certificate in Softlayer's "Add Certificate" wizard and to use it further with Local Load Balancer.

我搜索并尝试了以下openssl命令:

I googled and tried following openssl command:

openssl pkcs12 -in filename.pfx -nocerts -out key.pem

但是我最终得到了无效的"RSA PRIVATE KEY".请帮忙.

But I ended up with invalid "RSA PRIVATE KEY". Please help.

推荐答案

您的命令正确，并为您提供了PKCS#8格式的加密私钥.如果您需要未加密私钥，只需添加-nodes选项:

Your command is correct, and gives you the encrypted private key in PKCS#8 format. If you need the unencrypted private key, just add the -nodes option:

openssl pkcs12 -in filename.pfx -nocerts -nodes -out key.pem

如果您需要旧RSA格式的私钥，则应使用openssl pkcs8命令转换给定密钥:

If you need the private key in old RSA format, you should convert the given key with the openssl pkcs8 command:

openssl pkcs8 -in key.pem -out rsakey.pem

有关详细信息，请参阅文档:
