使用OpenSSL-Net将.der转换为.pem [英] Convert .der to .pem using OpenSSL-Net

问题描述

我有一个.der证书，该证书是二进制编码的，需要以编程方式在.net中转换为.pem文件

I have a .der certificate that is binary encoded which needs to be converted to a .pem file programatically in .net

此行在OSX上使用OpenSSL给出正确的输出:

This line gives the correct output using OpenSSL on OSX:

openssl x509 -inform der -in cert.crt -out cert.pem

但是我们需要在.net中做同样的事情

But we need to do the same in .net

我们尝试了许多解决方案，但完全陷入困境.

We have tried many solutions but are completely stuck.

会进行以下工作吗?

var oc = OpenSSL.X509.X509Certificate.FromDER(bio); 

任何建议都非常欢迎:)

Any advice very welcome :)

推荐答案

最后，我们能够使用它将DER导入到字符串中，然后可以将其导出到PEM:

In the end we were able to use this to import the DER into a string which we could then export to a PEM:

var oc = OpenSSL.X509.X509Certificate.FromDER(bio);

这些页面很有用:
