Minimum password lenght not enforced

[missbala]

Hey,

index.php says that wlan passwords should at least have 8 characters, but the actual minimum length is NOT enforced in function apply_config() . Instead password is written to hostapd.conf without further validation.

Thus, if user enters a password with less than 8 characters hostapd service fails to start (error message: password length must be at least 8 characters or something similar)

A one-liner javascript could address this issue (if lengh(pw1) < 8 .. FAIL WITH ERROR MESSAGE)
