At runtime yes, but only once when the configuration file is read; not
at each time there is a connection.

Yes, they should result in the same value. I asked you to try this to
make sure you had entered both the SSID and passphrase correctly.. I
would assume there was something else on the wpa_passphrase command
line. Please note that shell can change some special characters on the
command line and unless you carefully quote or escape the strings, you
may not get want you wanted.
