May I ask what is the topic of the academic project? Research on
unsecure encryption at any key length?

Replace WEP_KEY_LEN definition (couple of places) to use larger maximum
key length than 13, set host_encrypt and host_decrypt to 1, and you are
more or less done. I would search for other places using 13 (e.g.,
prism2_ioctl_siwencode()) and replace them with suitable maximum length.
These may also need some small changes to support more than two
different key length.

You will also need to make sure that the tools you are using to
configure keys (e.g., iwconfig) support the lengths you selected.
hostap_crypt_conf does not seem to care about the key length, so it
might work as-is.
