Android Question Firebase Auth, Facebook Key-Hash

i'm trying to generate Key-Hash for Facebook but i'm getting this error

The JKS keystore uses a proprietary format. It is recommended to migrate to PKCS12 which is an industry standard format using "keytool -importkeystore -srckeystore D:\Android\MyPSK.keystore -destkeystore D:\Android\MyPSK.keystore -deststoretype pkcs12".

there is anyway to ignore this warning and just create the Key-hash ?

and if there is not, if i migrated my key to PKCS12 i will be able to update my old signed apps on google play using the new PKCS12 key ?

I've just tested it with a keystore created with B4A and this command:
keytool -exportcert -alias B4A -keystore "key.keystore" | c:\OpenSSL-Win32\bin\openssl sha1 -binary | c:\OpenSSL-Win32\bin\openssl base64
It should ask for the password and then show the required key.
yes , it's asking for the password "and i'm sure its the right password"

i tried to create an other keystore, it shows the warning and i get the hash-key under it , the problem with my old key that i only get "Woxw" instead of of the hash-key
