如何从.crt文件转换.pem格式的证书？

Question

I have 4ec7049585ebc7.crt and gd_bundle.crt files. I want to convert it into pem format. I need two files one certificate and key in pem format. what is the openssl command for it.?

Answer 1

Check out Paul Heinlein's OpenSSL Command-Line HOWTO . Its got lots of recipes.

Do you know what format the files are currently in? They are probably already in PEM format. If not, you can simply try -inform ASN1 , -inform PEM , etc until you find something that does not error.

More than likely, you are going to have to breakout gd_bundle.crt with a script because its going to be full of PEM encoded certificates concatenated together.
