In some cases you might be forced to convert your private key to PEM format. To convert the certificates into different formats, you can use the following commands: openssl crl2pkcs7 -nocrl -certfile yourpemcertificate.crt -out yourpkcs7certificate.p7b -certfile CA-bundle.crt. In the folder you ran OpenSSL from you’ll find the certifcate (.crt) and the two private keys (encrypted and unencrypted).
This time you need to enter the new password that you created in step 1. Openssl rsa -in -out Īgain you need to enter an import password. So always be extra careful when it comes to private keys!

Fire up a command prompt and cd to the folder that contains your. So after you installed OpenSSL you can start it from it’s Bin folder. where you probably need to import the certificates and keyfiles in plain text (unencrypted).
