I'm on Android Pie and have two files:
* client certificate (extension is .crt, but inside looks like pem - starts with
* user key (extension is .key, inside again looks like pem, starts with
-----BEGIN PRIVATE KEY-----)
When I move the .crt file to android I'm able to install it (it says it is a client certificate), but I'm not able to install the .key part.
I tried converting the key to p12, but Android can't import that (it says that there is no certificate to install when I select it):
openssl pkcs12 -export -inkey my.key -in my.crt -out cert_key.p12
And few other commands (but I don't have the command written), but without success.
