Convert a .cer file to .pfx file

Question

My ultimate objective is to sign my exe.

For this i would need a certificate. From my company's pKI i got a .cer file and .p7b (certificate chain) file.

Now to sign an exe i need a .pfx file. So i want to convert a .cer file to .pfx file

For this i donwloaded openssl distribution.

Now issuing this command openssl pkcs12 -export -in certificatename.cer -inkey privateKey.key -out certificatename.pfx -certfile cacert.cer is resulting into unable to load certificates.

Does anyone have any hints on this ?

Answer 1

因此，如果你想在获得.cer文件后签署一个exe，那么诀窍就是执行以下步骤

1. 使用openssl命令将.cer转换为.pem
2. 使用openssl命令将.pem转换为.pfx
3. 使用signtool使用步骤2中生成的.pfx文件对.exe进行签名。

要转换的openssl命令，请检查此
