Where to download the .p12 file ?

See here:
https://cloud.google.com/storage/docs/authentication?hl=en
Service Account Authentication->Generating a private key

When you add new service account then the .p12 file will be download automatically to your PC.

Then use the
Service account->Email address
as
Service Account Name
in plugin

Thnaks i ahve managed to get the p12 file. Now since i am trying to run this on my localhost, i am attempting to store the the P12 file on my google drive, following the details in the help documentation. If i try to save the API key, i get the below message;

An error occurred: Unable to parse the p12 file. Is this a .p12 file? Is the password correct? OpenSSL error: error:0D0680A8:asn1 encoding routines:ASN1_CHECK_TLEN:wrong tag. Your settings could not be saved.

Where can i enter a password ?

Already figured it out, the p12 file name, can’t have any spaces in it, if you try to safe the configuration, the spaces are removed, hence the file name isn’t correct anymore.

However I created several times a new client-ID and p12-key, I constantly get following error:

An error occurred: Unable to parse the p12 file. Is this a .p12 file? Is the password correct? OpenSSL error: error:0D0680A8:asn1 encoding routines:ASN1_CHECK_TLEN:wrong tag. Your settings could not be saved.

It seems that this error is due to an invalid certificate format?
Or probably I did something wrong?
