how to use non password protected (.p12) ssl certificate in spring boot

Onki :

I have a .pem certificate which I have to use in my spring boot application. Now, since java does not understand .pem format, I am converting it to .p12 format.

Since, we already have a .pem certificate which is not protected by any password, I am trying to avoid password for .p12 too.

I created two .p12 files, one is with password using below command :

openssl x509 -signkey sslcert.key  -in sslcert.csr   -req -days 365
-out sslcert.pem

And another without password using below command :

openssl pkcs12  -inkey sslcert.key  -in sslcert.pem  -export -passout
pass: -nokeys -out sslcert.p12

And I am able to get the results successfully using the one with password using the below properties in spring boot application :

server.port=8443  
server.ssl.enabled=true 
server.ssl.key-store-type=PKCS12 
server.ssl.key-store=keys/sslcert.p12 
server.ssl.key-store-password=password

But when I am trying to use the one without password which is my preference, I am getting sslhandshake exception.

And also, I am not able to figure out how to pass this information to spring boot that ssl is not password protected.

SO far I tried many combinations like not passing password property or keeping it empty but it failed in all cases.

server.port=8443 
server.ssl.enabled=true
server.ssl.key-store-type=PKCS12
server.ssl.key-store=keys/sslcert.p12

I am getting below exception :

SO, can any one throw some light on how to use non-password protected .p12 certificate in spring boot.

All googles articles seems to be telling about the password propected. SO is it a mandatory thing in java?

Onki :

So after all the research, it seems java key store needs a password. So I had to ignore the .p12 which we had without password. And using the pem certificate, we converted it to .p12 with password. And I am doing this from spring code where I am passing random password to shell script which generates .p12 from .pem using that password.

And then I am passing the same password to ssl properties from the code.

one drawback is I have to regenerate .p12 from .pem every time application is restarted but this is how I prevent static password.
