gc.set_string('/apps/mobilehotspot/encryption_algo', 'WEP')
gc.set_string('/apps/mobilehotspot/encryption_key', 'key bytes')

note that the encryption key here is the actual bytes of the key, hotspot_backend.py will take care of hex-encoding them for iwconfig.

Also note that hotsport_backend.py will padd the key with zeroes to get it to exactly 13 bytes (and in case your set key is longer than 13 bytes it will trim it down ot 13bytes). You can see the exact hex-encoded key in hotspot_backend.py output when it calls iwconfig.

Note that my Mac laptop refused to even see the N900 hotspot when encryption was enabled so it might be that this does not actually work even if from the device POV it seems to.

To disable/re-enable encryption you can just unset/set the encryption_algo config key.
