With OpenSSL I created a certificate using the following.

openssl req -x509 -newkey rsa:4096 -keyout myKey.pem -out cert.pem -days 365 -nodes

=> Hitting enter on all prompts

openssl pkcs12 -export -out keyStore.p12 -inkey myKey.pem -in cert.pem -name "alias" -passout pass:123

=>Transferring keyStore.p12 and cert.pem to my android device (S10 )

=>Checked in cert.pem in settings

Then I tried to check In keyStore.p12: android settings > Biometrics and Security > Other Security Settings > Install from device storage > VPN and app user certificate > typed in the password “123”

Android returns “Invalid Password” but I know the password is correct (double checked it on my windows machine)

I've already tried to leave the password blank, restarted my phone and computer, generated a new certificate and verified the password multiple times etc.

I´m really at a loss here. thanks for any help in advance!

Found the answer on accident. I installed "Win64 OpenSSL v1.1.1n" and created the certificate wth that version instead of "Win64 OpenSSL v3.0.2", which resolved the problem
