如何从.net中的字符串读取X509签名证书内容？

Question

I have X509 Signing Certificate inside of a string like:

var signingCertificate = -----BEGIN CERTIFICATE-----\r\nMIICTjCCAbegAw.........-----END CERTIFICATE-----

Now I want to read the content of this certificate. i know we can do it using X509Certificate2 object but that reads from file directly. Is there anyway to read the content from string?

Answer 1

You can convert your string to byte array, and create a X509Certificate2 object from it.

byte[] bytes = Encoding.ASCII.GetBytes(signingCertificate);
var x509Certificate2 = new X509Certificate2(bytes);
