'what format is this "passcode" file? (found along a keystore)
A Globalprotect vpn client seems to use a keystore in pfx format + a pan_client_cert_passcode.dat file for which I want to find out what the format is (=how to decode it).
I happen to know the passphrase (8 characters), and the passcode file seems to be binary, 16 bytes.
What format could it be?

A .pfx file is a key store file. Its format is defined in PKCS12 (Public-Key Cryptography Standards #12).
Possible file endings for such a key store are: .pkcs12 .pfx .p12
To list the content of such a file see this post.
A .pfx file can be password protected (as in your case). Because you know the password you don't need a "passcode file". Your "passcode file" could be UTF-16 encoded. It could be the reason why the length is twice as long as the password. You could try a hex editor (XVI32 on Windows or ghex on linux) to see the content of the file.
