Q:

Export openssl key to file

I generated a private key using commend:
openssl genrsa -out privKey.pem

Now I want to export this key to file with extension .p12, so I used commend:
openssl pkcs12 -export -inkey privKey.pem -out key.p12 -name "MyPrivKey"

but when I try to run this commend via commend line, I have no results (it's running all time and doesn't stop), and when I open the file .p12 I have message: 
Could not display 'key.p12'
Reason: Unrecognized or unsupported data.

Can someone explain me, what I am doing wrong?

A:

You need to generate an crt file too.
openssl req -x509 -nodes -newkey rsa:2048 -days 1825 -out cert.crt -keyout key.key

then
openssl pkcs12 -export -inkey key.key -in cert.crt -out export.p12

if you have a CA file will be
openssl pkcs12 -export -inkey key.key -in cert.crt -certfile ca.crt -out export.p12
